I just found out about Snitz Forums and I wanted to ask whether it is possible to have forums which are password protected and not viewable to all members but only a group of members?
In addition to what Kat said, you also have the option of controlling which members can see a forum. You can even limit it to specific users AND have a password over it (although I can't see why you'd want to do that).
AND you can make forums visible, but only postable by certain members.
