If so, the answer is to install the netwide cancel and to also ask people to post changes rather than the article again. Multiple digests could be checked at ucbvax the way I suggested. (actually, with digests, simply a comparison on the header would be enough since it contains a unique issue number, but this assumes that later digests don't come out as corrections either) Naturally, comparison has to start after the header. One thing bothers me about the automatic cancel command. right now, anybody can call rnews, and that means anybody who knows what they are doing could send out a cancel request on my articles. I wouldn't like it if some censoring person decides he doesn't like somebody else's net.jokes.q entry and decides to cancel it!
