I don't know how mathforum works, but you cannot correct a message that has been posted to a large number of NNTP servers; you have to post a correction. I took a look at mathforum and I see that the mathforum post has been edited, but that only affects the mathforum post: <http://mathforum.org/kb/message.jspa?messageID=7085258&tstart=0> Rob Johnson <rob(a)trash.whim.org> take out the trash before replying to view any ASCII art, display article in a monospaced font

In fact, Usenet was built with the ability to supersede posts in order to correct errors, by canceling the old post and replacing it with the new. Because it was easy to forge cancels (and hence supersedes), few servers honor cancel requests these days. Of course, that probably has little to do with mathforum's edit functionality. Who knows how they implemented that and whether they bothered trying to propagate it to Usenet? -- Jesse F.

My newsserver accepted cancels and Supersedes when I last checked (I do recall this because there was a troll superseding someone's posts with vulgar drivel), and I see a 13/26. Or it could be that one of these servers doesn't propagate such messages: pitt.edu news.cse.ohio-state.edu news.glorb.com news2.glorb.com news.glorb.com tr22g12.aset.psu.edu news.mathforum.org -- Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald E.
