Stop Users Adding Own Categories?

[MikeJeffs]

I don't want my users to be able to create new categories. I just want 2 or 3 that I've created myself. I want all users to be able to post to all categories.

I'm sure this is really simple to do, but I can't see a setting for it.

Can anyone advise?
thanks!

There's a setting for each category that lets you tell it if users can create sub-categories to it or not.

Also, there's a setting in the usergroup permissions for each group, to tell if they can create categories or not.
