Thanks Allen. I'm still concerned though and perhaps i haven't conveyed the problem well.

Let's say we have group #1 whose members have access to a private forum "A". When I rename group #1 for a new group of users that will have access to private forum "B" won't the original users assigned to group #1 have access to forum "B"? And won't the new group of users assigned to group #1 have access to private forum "A"?

If so that's what I'm trying to avoid.

Thanking you in advance,
Dan Hill
