Thanks. 

The guy in charge of this bbs is, of course, looking to avoid work
(don't we all), so he was wondering about whether 7.1 was subject to
this vulnerability and the possible data loss bug.

I did a little research, and it looks like 7.1.3 is the last of the 7.1
line. Security Focus reports a boundary condition vulnerability for
7.1.3 from 2003. So it doesn't look wise to leave it at 7.1 forever, I
suppose.

I'm looking at the release notes for 7.2 and thinking that, when we make
the jump, jumping to 7.4 will probably be the best bet.

Any other suggestions? Any thoughts on the urgency of the move?
