Most pages in the wiki have one or more category tags. These tags serve both as an indication of the general subject area of the page and as an alternative navigation tool. By clicking on the category link (always found at the bottom of the page) you will be taken to a page that lists all of the pages containing that category tag. For example, if you click on the Category word of the 'Category: Help' links at the bottom of this page, you will be taken to a special page that lists all the categories that have been used in this wiki. When click a category name, like the Help word, the you will be taken to a page that has links to all help-related pages (or at least, all that have been so tagged).
