Allowing users to make their own catergories

Hey all. Try as I might, I can't find the option to allow users to make their own catergories. Well I have, but things aren't working.

The setup is I want users to make their own catergories under one catergory, I don't even know where they create them from. I had this set up at very first, but have long since disabled it so I don't remember how to get it working.

Any tips?

Edit the category and make sure the 'Allow Users to Create Sub-Categories' option is set to yes, then edit your usergroup permissions and make sure the 'Can create categories' option is set to yes. Your users will then be able to create categories through the 'Category Admin' link under the 'My Stuff' menu.

I must have missed the admin usergroup, can create catergories. w00tage!
