I need to implement several closed areas within a GT-forum installation. Only people who belong to a specific user group must have read and/or write access to that area. My wish would be to have an unlimited nummer of such groups and each registered user should be able to be a member of any of them if he is allowed by the "group moderator"

We need this to discuss internal issues on different topics before they get visible to the public.

Besides this it would be great if this could integrate seamless into the whole forum. If forums in that a user has neither read nor write access could be invisible to him, that would be great.
