How to make a forum act as a category?

[Bustah]

I've got my forums set up exactly the way I want them, but theres just one thing that isn't working right.

I've got forums with subforums underneath them. When I click on the forum, it brings me to the list of subforums, underneath those is where threads would be if forum posting was on. Now, its just a waste of space, no one can post there, so its pretty pointless for it to be there.

How can I remove it?
