Well, the subject says it all.

We've got a slew of unrealized long term gains.
We've also got a few members leaving.

Now, I've seen the withdrawl report and how they will be
responsible for their gains on a Schedule-D.

The question I've got is how can we account for those taxes
being paid (within the club) so that when we finally do sell
those securities, we can recognize that some of the
long-term capital gains taxes have already been paid, and
not pay it again.

Gotta be a common thing.
Thanks!
