bbPress.org

I have been googlng this for the past 4/5 days trying to find a solution and it seems im not alone.

There are a lot of people as surprised as me that this function is not available and from what i can read would also be willing to pay for it. If someone wrote a little plugin for this it could be worth their while.

Surely a way to restrict a forum or topic access cant be that difficult for someone in the know to create?
