Ye i missed it under Edit xD

One more question i am going to merge my website login and forum login how is password encrypted in punBB. My site uses sha1 username and password combo.

I want registration to be combined as well when someone registers for my page he also gets forum account but password needs to be encrypted the same.

Is there an extension that allows you to limit access to some forum to only a selected user group.

Say:

General Discussion - All registered users
Music - All registered users
VIP Discussion - Only members of VIP group
Admin Discussion - Only admins

Etc something that allows access regulation.
