Well, you have everything *they* got... assuming they didn't screw up
(we've all see that already, right?)  But as far as the base posts
from a given program source, as I suggested in a different posting, the
poster can serial number the posts, so you at least know whether you've
missed any.

It's my intuition, based on 20 years around the periphery of NNTP, that
it can be made much, much more reliable than it often appears. if your
clients are a little smarter than the average bear.
