site category not visible when creating a new site

Hi,

I want to create a new site in my MOSS 2007 environment and add a category to it.

Problem:

I cannot get the site category to be displayed!??!

It is driving me nuts!

What are the exact settings I need to perform to get this visible?! I've googled about 20 sites but alas.

Many Thanks in @vance!
