Hey all,

Is there any kind of module that does the following :
Forum or look a like

Only the poster and a selected group can reply on topics

The poster can select the best answer and lock the "question" or topic

If the poster selects an answer, the user of the selected group that made the answer gets a point (userpoint or reppoint or so)

And of course, a module that makes it possible to become a member of the selected group

Any help would be nice :)

Bert.
