just for the hell of it. Net.geeks People to whom the Net is Life, who worry about what happens when they graduate and they lose their free, 24-hour access. Net.gods The old-timers; the true titans of the Net and the keepers of its collective history. They were around when the Net consisted of a couple of computers tied together with baling wire. Lurkers Actually, you can't tell these people are there, but they are. They're the folks who read a newsgroup but never post or respond. Wizards People who know a particular Net-related topic inside and out. Unix wizards can perform amazing tricks with that operating system, for example. Net.saints Always willing to help a newcomer, eager to share their knowledge with those not born with an innate ability to navigate the Net, they are not as rare as you might think. Post a question about something and you'll often be surprised how many responses you get. The last group brings us back to the Net's oral tradition. With few written guides, people have traditionally learned their way around the Net by asking somebody, whether at the terminal next to them or on the Net itself. That tradition continues: if you have a question, ask. Today, one of the places you can look for help is in the `news.newusers.questions' newsgroup, which, as its name suggests, is a place to learn more about Usenet. But be careful what you post. Some of the Usenet wizards there get cranky sometimes when they have to answer the same question over and over again. Oh, they'll eventually answer your question, but not before they tell you should have asked your host system administrator first or looked at the postings in `news.announce.newusers'. ôhe First Amendment as Local OrdinaÐÓÅ ====================================== Usenet's international reach raises interesting legal questions that have yet to be fully resolved. Can a discussion or posting that is legal in one country be transmitted to a country where it is against the law? Does the posting even become illegal when it reaches the border? And what if that country is the only path to a third country where the message is legal as well? Several foreign colleges and other institutions have cut off feeds of certain newsgroups where Americans post what is, in the U.S., perfectly legal discussions of drugs or alternative sexual practices. Even in the U.S., some universities have discontinued certain newsgroups their administrators find offensive, again, usually in the `alt.*' hierarchy. rn Commands =========== Different commands are available to you in rn depending on whether you are already in a newsgroup or reading a specific article. At any point, typing a lower-case `h' will bring up a list of available commands and some terse instructions for using them. Here are some of them: After you've just called up rn, or within a newsgroup: `c' Marks every article in a newsgroup as read (or "caught up") so that you don't have to see them again. The system will ask you if you are sure. Can be done either when asked if you want to read a particular newsgroup or once in the newsgroup. `g' Goes to a newsgroup, in this form: `g news.group' Use this both for going to groups to which you're already subscribed and subscribing to new groups. `h' Provides a list of available commands with terse instructions. `l' Gives a list of all available newsgroups. `p' Goes to the first previous subscribed newsgroup with un-read articles. `q' Quits, or exits, rn if you have not yet gone into a newsgroup. If you are in a newsgroup, it quits that one and brings you to the next subscribed newsgroup. Only within a newsgroup: `=' Gives a list of all available articles in the newsgroup. `m' Marks a specific article or series of articles as "un-read" again so that you can come back to them later. Typing `1700m' and hitting enter would mark just that article as un-read. Typing `1700-1800m' and hitting enter would mark all of those articles as un-read. `s file' Copies the current article to a file in your News directory, where "file" is the name of the file you want to save it to. You'll be asked if you want to use "mailbox" format when saving. If you answer by hitting your `N' key, most of the header will not be saved. `space' Brings up the next page of article listings. If already on the last page, displays the first article in the newsgroup. `u' Un-subscribe from the newsgroup. `/text/' Searches through the newsgroup for articles with a specific word or phrase in the "subject:" line, from the current article to the end of the newsgroup. For example, `/EFF/' would bring you to the first article with "EFF" in the "subject:" line. `?text?' The same as above except it searches in reverse order from the current article. Only within a specific article: `C' If you post an article and then decide it was a mistake, call it up on your host system and hit this. The message will soon begin disappearing on systems around the world. `F' Post a public response in the newsgroup to the current article. Includes a copy of her posting, which you can then edit down using your host system's text editor. `f' The same as above except it does not include a copy of the original message in yours. `m' Marks the current article as "un-read" so that you can come back to it later. You do not have to type the article number. `Control-N' Brings up the first response to the article. If there is no follow-up article, this returns you to the first unread article in the newsgroup). `Control-P' Goes to the message to which the current article is a reply. `n' Goes to the next unread article in the newsgroup. `N' Takes you to the next article in the newsgroup even if you've already read it. `q' Quits, or exits, the current article. Leaves you in the current newsgroup. `R' Reply, via e-mail only, to the author of the current article. Includes a copy of his message in yours. `r' The same as above, except it does not include a copy of his article. `s |mail' user Mails a copy of the article to somebody. For "user" substitute her e-mail address. Does not let you add comments to the message first, however. `space' Hitting the space bar shows the next page of the article, or, if at the end, goes to the next un-read article. Ðn Commands =========== To mark a specific article for reading, type the letter next to it (in lower case). To mark a specific article and all of its responses, type the letter and an asterisk, for example: a* To un-select an article, type the letter next to it (again, in lower case). `C' Cancels an article (around the world) that you wrote. Every article posted on Usenet has a unique ID number. Hitting a capital `C' sends out a new message that tells host systems that receive it to find earlier message and delete it. `F' To post a public response, or follow-up. If selected while still on a newsgroup "page", asks you which article to follow up. If selected while in a specific article, will follow up that article. In either case, you'll be asked if you want to include the original article in yours. Caution: puts you in whatever text editor is your default. `N' Goes to the next subscribed newsgroup with unread articles. `P' Goes to the previous subscribed newsgroup with unread articles. `G news.group' Goes to a specific newsgroup. Can be used to subscribe to new newsgroups. Hitting `G' brings up a sub-menu: `u' Goes to the group and shows only un-read articles. `a' Goes to the group and shows all articles, even ones you've already read. `s' Will show you only articles with a specific subject. `n' Will show you only articles from a specific person. `M' Mails a copy of the current article to somebody. You'll be asked for the recipient's e-mail address and whether you want to add any comments to the article before sending it off. As with `F', puts you in the default editor. `:post' Post an article. You'll be asked for the name of the group. `Q' Quit, or exit, nn. `U' Un-subscribe from the current newsgroup. `R' Responds to an article via e-mail. `space' Hitting the space bar brings up the next page of articles. `X' If you have selected articles, this will show them to you and then take you to the next subscribed newsgroup with unread articles. If you don't have any selected articles, it marks all articles as read and takes you to the next unread subscribed newsgroup. `=word' Finds and marks all articles in the newsgroup with a specific word in the "subject:" line, for example: `=modem' `Z' Shows you selected articles immediately and then returns you to the current newsgroup. `?' Brings up a help screen. `<' Goes to the previous page in the newsgroup. `>' Goes to the next page in the newsgroup. `$' Goes to the last page in an article. `^' Goes to the first page in an article. Some Usenet hints ================= Case counts in Unix - most of the time. Many Unix commands, including many of those used for reading Usenet articles, are case sensitive. Hit a `d' when you meant a `D' and either nothing will happen, or something completely different from what you expected will happen. So watch that case! In nn, you can get help most of the time by typing a question mark (the exception is when you are writing your own message, because then you are inside the text-processing program). In rn, type a lower-case `h' at any prompt to get some online help. When you're searching for a particular newsgroup, whether through the l command in rn or with nngrep for nn, you sometimes may have to try several keywords. For example, there is a newsgroup dedicated to the GRATEFUL DEAD, but you'd never find it if you tried, say, `l grateful dead', because the name is `rec.music.gdead'. In general, try the smallest possible part of the word or discussion you're looking for, for example, use "trek" to find newsgroups about "Star Trek." If one word doesn't produce anything, try another. óross-posting ============= Sometimes, you'll have an issue you think should be discussed in more than one newsgroup. Rather than posting individual messages in each group, you can post the same message in several groups at once, through a process known as cross-posting. Say you want to start a discussion about the political ramifications of importing rare tropical fish from Brazil. People who read `rec.aquaria' might have something to say. So might people who read `alt.politics.animals' and `talk.politics.misc'. Cross-posting is easy. When you get ready to post a message (whether through Pnews for rn or the `:post' command in nn), you'll be asked in which newsgroups. Type the names of the various groups, separated by a comma, but no space, for example: rec.aquaria,alt.politics.animals,talk.politics.misc and hit enter. After answering the other questions (geographic distribution, etc.), the message will be posted in the various groups (unless one of the groups is moderated, in which case the message goes to the moderator, who decides whether to make it public). It's considered bad form to post to an excessive number of newsgroups, or inappropriate newsgroups. Chances are, you don't really have to post something in 20 different places. And while you may think your particular political issue is vitally important to the fate of the world, chances are the readers of `rec.arts.comics' will not, or at least not important enough to impose on them. You'll get a lot of nasty e-mail messages demanding you restrict your messages to the "appropriate" newsgroups. ôhe Brain-tumor Boy and the Modem TaÈ ===================================== Net users sometimes like to think they are smarter or somehow better than everybody else. They're not. If they were, nobody on the Net would ever have heard of Craig Shergold, the Brain-Tumor Boy, or the evil FCC's plan to tax your modem. Alas, both of these online urban legends are here to stay. Just when they seem to have died off, somebody posts a message about one or the other, starting a whole new round of flame wars on the subject. For the record, here are the stories on both of them: Craig Shergold -------------- There once was a seven-year-old boy in England named Craig Shergold who was diagnosed with a seemingly incurable brain tumor. As he lay dying, he wished only to have friends send him postcards. The local newspapers got a hold of the tear-jerking story. Soon, the boy's wish had changed: he now wanted to get into the Guinness Book of World Records for the largest postcard collection. Word spread around the world. People by the millions sent him postcards. Miraculously, the boy lived. An American billionaire even flew him to the U.S. for surgery to remove what remained of the tumor. And his wish succeeded beyond his wildest dreams - he made the Guinness Book of World Records. But with Craig now well into his teens, his dream has turned into a nightmare for the post office in the small town outside London where he lives. Like Craig himself, his request for cards just refuses to die, inundating the post office with millions of cards every year. Just when it seems like the flow is slowing, along comes somebody else who starts up a whole new slew of requests for people to send Craig post cards (or greeting cards or business cards - Craig letters have truly taken on a life of their own and begun to mutate). Even Dear Abby has asked people to stop! What does any of this have to do with the Net? The Craig letter seems to pop up on Usenet as often as it does on cork boards at major corporations. No matter how many times somebody like Gene Spafford posts periodic messages to ignore them or spend your money on something more sensible (a donation to the local Red Cross, say), somebody manages to post a letter asking readers to send cards to poor little Craig. The Modem Tax ------------- In 1987, the Federal Communications Commission considered removing a tax break it had granted CompuServe and other large commercial computer networks for use of the national phone system. The FCC quickly reconsidered after alarmed users of bulletin-board systems bombarded it with complaints about this "modem tax." Now, every couple of months, somebody posts an "urgent" message warning Net users that the FCC is about to impose a modem tax. This is NOT true. The way you can tell if you're dealing with the hoax story is simple: it ALWAYS mentions an incident in which a talk-show host on KGO radio in San Francisco becomes outraged on the air when he reads a story about the tax in the New York Times. Another way to tell it's not true is that it never mentions a specific FCC docket number or closing date for comments. Save that letter to your congressman for something else. Big Sig ======= There are .sigs and there are .sigs. Many people put only bare-bones information in their .sig files - their names and e-mail addresses, perhaps their phone numbers. Others add a quotation they think is funny or profound and a disclaimer that their views are not those of their employer. Still others add some ASCII-art graphics. And then there are those who go totally berserk, posting huge creations with multiple quotes, hideous ASCII "barfics" and more e-mail addresses than anybody could humanly need. College freshmen unleashed on the Net seem to excel at these. You can see the best of the worst in the `alt.fan.warlord' newsgroup, which exists solely to critique .sigs that go too far, such as: ___________________________________________________________________________ |#########################################################################| |#| |#| |#| ***** * * ***** * * ***** ***** ***** |#| |#| * * * * ** ** * * * * |#| |#| * ****** *** * * * *** * ** ***** ***** |#| |#| * * * * * * * * * * * |#| |#| * * * ***** * * ***** ***** * * |#| |#| |#| |#| **** ***** ***** ***** ***** ***** ***** ***** |#| |#| * ** * * * * * * * * |#| |#| **** * * ** ***** * * ** * * * |#| |#| * ** * * * ** * * * * * * * |#| |#| **** ***** ***** ** ***** ***** ***** ***** ***** |#| |#| |#| |#| T-H-E M-E-G-A B-I-G .S-I-G C-O-M-P-A-N-Y |#| |#| ~-----------------------------~ |#| |#| "Annoying people with huge net.signatures for over 20 years..." |#| |#| |#| |#|---------------------------------------------------------------------|#| |#| "The difference between a net.idiot and a bucket of shit is that at |#| |#| least a bucket can be emptied.

Killfiles are just the thing for you. When you start your newsreader, it checks to see if you have any lists of words, phrases or names you don't want to see. If you do, then it blanks out any messages containing those words. Such as cascades. As you saw earlier, when you post a reply to a message and include parts of that message, the original lines show up with a > in front of them. Well, what if you reply to a reply? Then you get a >> in front of the line. And if you reply to that reply? You get >>>. Keep this up, and soon you get a triangle of >'s building up in your message. There are people who like building up these triangles, or cascades. They'll "respond" to your message by deleting everything you've said, leaving only the "In message 123435, you said:" part and the last line of your message, to which they add a nonsensical retort. On and on they go until the triangle has reached the right end of the page. Then they try to expand the triangle by deleting one with each new line. Whoever gets to finish this mega-triangle wins. There is even a newsgroup just for such folks: alt.cascade. Unfortunately, cascaders would generally rather cascade in other newsgroups. Because it takes a lot of messages to build up a completed cascade, the targeted newsgroup soon fills up with these messages. Of course, if you complain, you'll be bombarded with messages about the First Amendment and artistic expression - or worse, with another cascade. The only thing you can do is ignore them, by setting up a killfile. There are also certain newsgroups where killfiles will come in handy because of the way they are organized. For example, readers of `rec.arts.tv.soaps' always use an acronym in their subject: line for the show they're writing about (AMC, for example, for "All My Children"). This way, people who only want to read about "One Life to Live" can blank out all the messages about "The Young and the Restless" and all the others (to keep people from accidentally screening out messages that might contain the letters "gh" in them, "General Hospital" viewers always use "gh:" in their subject lines). Both nn and rn let you create killfiles, but in different ways. To create a killfile in nn, go into the newsgroup with the offending messages and type a capital `K'. You'll see this at the bottom of your screen: AUTO (k)ill or (s)elect (CR => Kill subject 30 days) If you hit return, nn will ask you which article's subject you're tired of. Chose one and the article and any follow-ups will disappear, and you won't see them again for 30 days. If you type a lower-case `k' instead, you'll get this: AUTO KILL on (s)ubject or (n)ame (s) If you hit your `S' key or just enter, you'll see this: KILL Subject: (=/) Type in the name of the offending word or phrase and hit enter. You'll then be prompted: KILL in (g)roup 'eff.test' or in (a)ll groups (g) except that the name of the group you see will be the one you're actually in at the moment. Because cascaders and other annoying people often cross-post their messages to a wide range of newsgroups, you might consider hitting `a' instead of `g'. Next comes: Lifetime of entry in days (p)ermanent (30) The P key will screen out the offending articles forever, while hitting enter will do it for 30 days. You can also type in a number of days for the blocking. Creating killfiles in rn works differently - its default killfile generator only works for messages in specific groups, rather than globally for your entire newsgroup list. To create a global killfile, you'll have to write one yourself. To create a killfile in rn, go into the newsgroup where the offending messages are and type in its number so you get it on your screen. Type a capital `K'. From now on, any message with that subject line will disappear before you read the group. You should probably choose a reply, rather than the original message, so that you will get all of the followups (the original message won't have a "Re: " in its subject line). The next time you call up that newsgroup, rn will tell you it's killing messages. When it's done, hit the space bar to go back into reading mode. To create a "global" kill file that will automatically wipe out articles in all groups you read, start rn and type control-K. This will start your whatever text editor you have as your default on your host system and create a file (called `KILL', in your `News' subdirectory). On the first line, you'll type in the word, phrase or name you don't want to see, followed by commands that tell rn whether to search an entire message for the word or name and then what to do when it finds it. Each line must be in this form /pattern/modifier:j "Pattern" is the word or phrase you want rn to look for. It's case-insensitive: both "test" and "Test" will be knocked out. The modifier tells rn whether to limit its search to message headers (which can be useful when the object is to never see messages from a particular person): `a:' Looks through an entire message `h:' Looks just at the header You can leave out the modifier command, in which case rn will only look at the subject line of messages. The `j' at the end tells rn to screen out all articles with the offending word. So if you never want to see the word "foo" in any header, ever again, type this: /foo/h:j This is particularly useful for getting rid of articles from people who post in more than one newsgroup, such as cascaders, since an article's newsgroup name is always in the header. If you just want to block messages with a subject line about cascades, you could try: /foo/:j To kill anything that is a followup to any article, use this pattern: /Subject: *Re:/:j When done writing lines for each phrase to screen, exit the text editor as you normally would, and you'll be put back in rn. One word of caution: go easy on the global killfile. An extensive global killfile, or one that makes frequent use of the `a:' modifier can dramatically slow down rn, since the system will now have to look at every single word in every single message in all the newsgroups you want to read. If there's a particular person whose posts you never want to see again, first find his or address (which will be in the "from:" line of his postings) and then write a line in your killfile like this: /From: *name@address\.all/h:j Usenet HistorÕ ============== In the late 1970s, Unix developers came up with a new feature: a system to allow Unix computers to exchange data over phone lines. In 1979, two graduate students at Duke University in North Carolina, TOM TRUSCOTT and JIM ELLIS, came up with the idea of using this system, known as UUCP (for Unix-to-Unix CoPy), to distribute information of interest to people in the Unix community. Along with STEVE BELLOVIN, a graduate student at the University of North Carolina and STEVE DANIEL, they wrote conferencing software and linked together computers at Duke and UNC. Word quickly spread and by 1981, a graduate student at Berkeley, MARK HORTON and a nearby high school student, MATT GLICKMAN, had released a new version that added more features and was able to handle larger volumes of postings - the original North Carolina program was meant for only a few articles in a newsgroup each day. Today, Usenet connects tens of thousands of sites around the world, from mainframes to Amigas. With more than 3,000 newsgroups and untold thousands of readers, it is perhaps the world's largest computer network. When things go wrong: ===================== * When you start up rn, you get a "warning" that "bogus newsgroups" are present. Within a couple of minutes, you'll be asked whether to keep these or delete them. Delete them. Bogus newsgroups are newsgroups that your system administrator or somebody else has determined are no longer needed. * While in a newsgroup in rn, you get a message: "skipping unavailable article." This is usually an article that somebody posted and then decided to cancel. FYI: ==== Leanne Phillips periodically posts a list of frequently asked questions (and answers) about use of the rn killfile function in the `news.newusers.questions' and `news.answers' newsgroups on Usenet. Bill Wohler posts a guide to using the nn newsreader in the `news.answers' and `news.software' newsgroups. Look in the `news.announce.newusers' and `news.groups' newsgroups on Usenet for "A Guide to Social Newsgroups and Mailing Lists", which gives brief summaries of the various `soc.*' newsgroups. "Managing UUCP and Usenet" by Tim O'Reilly and Grace Todino (O'Reilly & Associates, 1992) is a good guide for setting up your own Usenet system. *"Welcome, to the watering hole, to the death of objectivity, and the killing fields of the wide boys, where are we now..."* -- Marillion, "The Thieving Magpie (La Gazza Ladra)" Used in concerts as spoken intro by Fish to the 2nd part of "Misplaced Childhood"  * Mailing Lists and Bitnet *  ************************ Usenet is not the only forum on the Net. Scores of "mailing lists" represent another way to interact with other Net users. Unlike Usenet messages, which are stored in one central location on your host system's computer, mailing-list messages are delivered right to your e-mail box, unlike Usenet messages. You have to ask for permission to join a mailing list. Unlike Usenet, where your message is distributed to the world, on a mailing list, you send your messages to a central moderator, who either re-mails it to the other people on the list or uses it to compile a periodic "digest" mailed to subscribers. Given the number of newsgroups, why would anybody bother with a mailing list? Even on Usenet, there are some topics that just might not generate enough interest for a newsgroup; for example, the Queen list, which is all about the late FREDDIE MERCURY's band; or the Marillion & Fish list called "Freaks." And because a moderator decides who can participate, a mailing list can offer a degree of freedom to speak one's mind (or not worry about net.weenies) that is not necessarily possible on Usenet. Several groups offer anonymous postings - only the moderator knows the real names of people who contribute. Examples include 12Step, where people enrolled in such programs as Alcoholics Anonymous can discuss their experiences, and sappho, a list limited to gay and bisexual women. You can find mailing addresses and descriptions of these lists in the `news.announce.newusers' newsgroup with the subject of "Publicly Accessible Mailing Lists." Mailing lists now number in the hundreds, so this posting is divided into three parts. If you find a list to which you want to subscribe, send an e-mail message to list-request@address where "list" is the name of the mailing list and "address" is the moderator's e-mail address, asking to be added to the list. Include your full e-mail address just in case something happens to your message's header along the way, and ask, if you're accepted, for the address to mail messages to the list. ÷itnet ====== As if Usenet and mailing lists were not enough, there are Bitnet "discussion groups" or "lists." Bitnet is an international network linking colleges and universities, but it uses a different set of technical protocols for distributing information than the Internet or Usenet. It offers hundreds of discussion groups, comparable in scope to Usenet newsgroups. One of the major differences is the way messages are distributed. Bitnet messages are sent to your mailbox, just as with a mailing list. However, where mailing lists are often maintained by a person, all Bitnet discussion groups are automated - you subscribe to them through messages to a "listserver" computer. This is a kind of robot moderator that controls distribution of messages on the list. In many cases, it also maintains indexes and archives of past postings in a given discussion group, which can be handy if you want to get up to speed with a discussion or just search for some information related to it. Many Bitnet discussion groups are now "translated" into Usenet form and carried through Usenet in the `bit.listserv.*' hierarchy. In general, it's probably better to read messages through Usenet if you can. It saves some storage space on your host system's hard drives. If 50 people subscribe to the same Bitnet list, that means 50 copies of each message get stored on the system; whereas if 50 people read a Usenet message, that's still only one message that needs storage on the system. It can also save your sanity if the discussion group generates large numbers of messages. Think of opening your e-mailbox one day to find 200 messages in it - 199 of them from a discussion group and one of them a "real" e-mail message that's important to you. Subscribing and canceling subscriptions is done through an e-mail message to the listserver computer. For addressing, all listservers are known as "listserv" (yep) at some Bitnet address. This means you will have to add `.bitnet' to the end of the address, if it's in a form like this: `listserv@miamiu'. For example, if you have an interest in environmental issues, you might want to subscribe to the Econet discussion group. To subscribe, send an e-mail message to listserv@miamiu.bitnet Some Bitnet listservers are also connected to the Internet, so if you see a listserver address ending in `.edu', you can e-mail the listserver without adding `.bitnet' to the end. Always leave the "subject:" line blank in a message to a listserver. Inside the message, you tell the listserver what you want, with a series of simple commands: `subscribe group *Your Name*' To subscribe to a list, where group is the list name and *Your Name* is your full name, for example: `subscribe econet Henry Fielding' `unsubscribe group *Your Name*' To discontinue a group, for example: `unsubscribe econet Henry Fielding' `list global' This sends you a list of all available Bitnet discussion groups. But be careful - the list is VERY long! `get refcard' Sends you a list of other commands you can use with a listserver, such as commands for retrieving past postings from a discussion group. Each of these commands goes on a separate line in your message (and you can use one or all of them). If you want to get a list of all Bitnet discussion groups, send e-mail to listserv@bitnic.educom.edu Leave the "subject:" line blank and use the list global command. When you subscribe to a Bitnet group, there are two important differences from Usenet. First, when you want to post a message for others to read in the discussion group, you send a message to the group name at its Bitnet address. Using Econet as an example, you would mail the message to: econet@miamiu.bitnet Note that this is different from the listserv address you used to subscribe to the group to begin with. Use the listserv address ONLY to subscribe to or unsubscribe from a discussion group. If you use the discussion-group address, your message will go out to every other subscriber, many of whom will think unkind thoughts, which they may share with you in an e-mail message). The second difference relates to sending an e-mail message to the author of a particular posting. Usenet newsreaders such as rn and nn let you do this with one key. But if you hit your `R' key to respond to a discussion-group message, your message will go to the listserver, and from there to everybody else on the list! This can prove embarrassing to you and annoying to others. To make sure your message goes just to the person who wrote the posting, take down his e-mail address from the posting and then compose a brand-new message to him. Remember, also, that if you see an e-mail address like , it's a Bitnet address. Two Bitnet lists will prove helpful for delving further into the network. NEW-LIST tells you the names of new discussion groups. To subscribe, send a message to : sub NEW-LIST Your Name INFONETS is the place to go when you have questions about Bitnet. It is also first rate for help on questions about all major computer networks and how to reach them. To subscribe, send e-mail to : sub INFONETS Your Name Both of these lists are also available on Usenet, the former as `bit.listserv.new-list'; the latter as `bit.listserv.infonets' (sometimes `bit.listserv.info-nets'). *"It wasn't long before the invention of the mailing-list, an ARPANET broadcasting technique in which an identical message could be sent automatically to large number of network subscribers. Interestingly, one of the first really big mailing-list was "SF-LOVERS", for Science Fiction fans. Disscussing science fiction on the network was not work-related and was frowned upon by many ARPANET computer administrators, but this didn't stop it from happening."* -- Bruce Sterling, F&SF Science Column #5 "Internet"  * Telnet (Mining the Net, part I) *  ******************************* Like any large community, cyberspace has its libraries, places you can go to look up information or take out a good book. Telnet is one of your keys to these libraries. *Telnet* is a program that lets you use the power of the Internet to connect you to databases, library catalogs, and other information resources around the world. Want to see what the weather's like in Vermont? Check on crop conditions in Azerbaijan? Get more information about somebody whose name you've seen online? Telnet lets you do this, and more. Alas, there's a big "but!" Unlike the phone system, Internet is not yet universal; not everybody can use all of its services. Almost all colleges and universities on the Internet provide telnet access. So do the WELL, Netcom and the World. But the Free-Net systems do not give you access to every telnet system. And if you are using a public-access UUCP or Usenet site, you will not have access to telnet. The main reason for this is cost. Connecting to the Internet can easily cost $1,000 or more for a leased, high-speed phone line. Some databases and file libraries ca
