Categories are an important feature on wikis. Creating a category is easy: you just have to write a category name onto the page and you are done. !MoinMoin even simplifies this by letting you choose from a list of available categories while you are editing the page. By the way, this page is in the category CategoryCategory.

On the page of the category, you can give a brief description of the category's contents. If you want to get a list of all pages in that particular category, either click the title of the category or insert a suitable macro which lists the pages:

 * `<<FullSearch(Category``Samples)>>` lists all pages in the category `CategorySamples` (alternative you can use `<<FullSearch(@``PAGE@)>>`)
 * `<<FullSearch(r:CategoryRecipes\b -r:CategoryCake\b)>>` lists every recipe if it is not about a cake :-)
 * See HelpOnSearching for further information about the syntax.

Normally, categories have to be named like `Category``Something`. If you want to allow other patterns like `Catégorie``Gaffeur` (that is French by the way), then the administrator needs to change the configuration option `page_category_regex` according to the users' language. In a hebrew wiki, you would use `page_category_regex = '^Category[A-Z]|^קטגוריה .+'`. See HelpOnConfiguration.

The best choice is to create category pages from a CategoryTemplate (see HelpOnTemplates).
