Aus SubmersWiki

• A category is a software feature of MediaWiki. Categories provide automatic indexes that are useful as tables of contents. Together with links and templates they structure a project.
• Each of the pages in the Category namespace represents a so-called category, a kind of grouping of related pages. When a page belongs to one or more categories, this information appears at the bottom of the page (or in the upper-right corner, depending on the skin being used).
• You can assign a category to a page simply by adding "[[Category:Category name]]" to the page's wikitext source.

So as to reference a category within a page as a normal wiki link (without adding the page to the category) you should prefix the link name with a colon. For example: [[:Category:Not in this category]].
