So far, I have seen no copies of the worm on usenet. This may be
the result of my paying $$$ to a good usenet provider (Supernews.)
Unfortunately, my e-mail provider got the stupid idea that "delete"
meant "save a complete copy for 14 days just in case you want
to see it." Most of the stuff is going into two mailboxes that I need
to clean out manually every two or three hours (they're not my inbox,
so the POP3 script won't do it.)

It looks like two worms that just happened to hit at one time,
doesn't it?
