When you're not getting any posts from the FFML, you should try
resubcribing. If that doesn't work, assume it's dead. At least
that's the way I operate.
Unfortunately, some people seem to prefer asking other people whether
the list is dead when they don't get any posts. Even worse, a few of
them even ask whether the list is dead directly on the list, which
delays the resurrection of the list.
Thus I am making a list status checker available on the Web. It's at
the FFML homepage <http://illusion.snu.ac.kr/~wacko/ffml/>, and is
apparently working. It isn't perfect, but it should work in most
cases.
Anyways, congratulations to the moderator for successfully upgrading
the server!
