In newsgroups such as news.announce.newusers, there are periodic posting of such things as "How to post on USENET" and such introductory material. Usually there are more than one version of the same article exist at the same time. Is there a way to KILL the superceded article upon receipt of the new one? I believe that one of the header lines is "supercede such-and-such". Maybe that could be used? BTW, I've RTFM and just can't figure it out. Thanks in advance. William Lai

C News, as of the 10 Jan 90 patch, now will handle the Supercedes: header directly in relaynews. The original article is cancelled. Prior to this you had to use $NEWSBIN/expire/superkludge to get the supercedes header to work, and then it only did it in the groups named on the command line. Now superceding is done a little bit more efficiently at the cost of a slightly less efficient relaynews. As far as I know, which in this case is only memories of when we were a B News site, supercedes are not done by B 2.11 but they might be in the most recently releases. (If so, someone who hopefully point that out -- if not, then you could use a modified superkludge.) The possibility that Supercedes: is not done by B News is somewhat corroborated by the fact that the header is not mentioned in Section 2 of RFC 1036. One further note on superkludge: it only removes the file of the superceded article. References to the file in lib/history* will remain until the article expires normally. I don't know how other news systems deal with Supercedes:.
