Let Usergroups Create Private Forums

[ChurchMedia]

I would love to see a hack that would allow certain usergroups to create their own private forum. So from a page with a form on it, it would have:

---> Usergroup Name
---> Forum Name
---> Password Protect

Then the form would create the forum and the usergroup w/permissions to see the new forum. The one who created the private forum could then point other users to their forum along with the password for it.

Has that been done? Thanks!
