I fixed the problem -- and I think it affected everyone, not just Free
Agent -- I introduced a stoopit bugaboo when I diddled with the cancel mods
last week. Here's a repost of the article I posted 2 days ago right before
the groups were wiped:

Shame on me -- it was my fault. I didn't understand (and may still not)
all the subtleties of the code change I made 2-3 days ago when I made the
cancelling rename article files instead of actually deleting them.
Turns out CNews's implementation GROUP command in NNTP scans the directory
(for a newsgroup) on the fly counting articles. A snippet of relevant code
from scandir.c:
while ((dirent = readdir(dirp)) != NULL) {
artnum = atoi(dirent->d_name);
if (artnum == 0 || artnum < low_msg || artnum > high_msg)
continue;
So the cancelled files like
260!
were matching in this section of code as regular articles, since atoi()
returns an integer up to a non-digit character. Derrr. And this was
throwing off the counts when the GROUP command said how many articles
existed.
So. Names like
_260
do not confuse the code above. God forbid if they confuse some other
obscure little chunk of code! I never would have guessed it was scanning
the directory on-the-fly. But then again it'll be cached in memory and
still quite fast under Unix.
