add groups to moderate forums, not just users

[aussiev8]

hey,
i've come from using phpbb2 and the only feature i miss is the ability to add users to a group, lets say "forum1moderators" and then add that group to moderate that forum, rather then adding all the individuals to that forum as moderators..

Seriouslly, it takes ages, and is really annoying when wanting to remove or add another moderator, if something like this doesn't exist! someone should do it! This is pure convience!
