Thread:Project:Support desk/newbie question regarding user permissions

One of the sites that I manage has a long-neglected wiki, setup long before I took over.

The way our wiki works is that a user can only see the Categories they're assigned to (in our case, a Category = a committee). I can create a new user, but cannot find any options for assigning them to a category.

Any help would be greatly appreciated.

MediaWiki: 1.4.7 PHP: 5.2.11 (apache2handler) MySQL: 5.0.45-log
