/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 her 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
4.3 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.
4.4 THE BRAIN-TUMOR BOY, THE MODEM TAX AND THE CHAIN LETTER
Like the rest of the world, Usenet has its share of urban legends and questionable activities. There are three in particular that plague the network. Spend more than, oh, 15 minutes within Usenet and you're sure to run into the Brain Tumor Boy, the plot by the evil FCC to tax your modem and Dave Rhode's miracle cure for poverty. For the record, here's the story on all of them: 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 been powerless to make it 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. Don't send any cards to the Federal Communications Commission, either. In 1987, the FCC 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. Sooner or later, you're going to run into a message titled "Make Money Fast." It's your basic chain letter. The Usenet version is always about some guy named Dave Rhodes who was on the verge of death, or something, when he discovered a perfectly legal way to make tons of money — by posting a chain letter on computer systems around the world. Yeah, right.
