And here are 2 screenshots from the most important sections:

1. Categories
2. Usergroup permissions

As you can see has the most of the wanted features. eg Per Category you can setup different group permissions for posting, different rating questions, different extra fields etc. Also in usergroup permissions, nothing is missing. See the screenshoots carefully.

As most of you already wrote, vBulletin lacks in performance in big boards (lots of forums). Even if I've added the feature to have a discussion forum, I'm giving you 3 ways to eliminate the total number of forums:

1. You can set some (not so important) categories, to not have forum. They'll have reviews, but not native vB Forums.
2. You can set which usergroup can has Forums and which not.
3. Even usergroups which have permission for threads, the author can decide per post (article/review) if he was a thread or not.

Thank you
Chris
