A category is a WikiName that exploits WikiWiki's reverse linking: if you click on the title of a category page, you'll get a list of pages belonging to that category. To get a list of all categories, click the CategoryCategory title in the navigation area.

Additionally, you can add lists of all pages which are members of that particular category to the category page using macros like this:

Here is a list of all categories known to this wiki: --> -->
