This web site makes extensive use of tags, called categories in MediaWiki, to flag pages as being related to different topics. Category tags are an alternative way to navigate the web site. Users are encouraged to add tags to pages when they create or modify them. We strive to have each page have at least one category tag associated with it.
The category tags used in this web site are shown on here as a tag cloud. The font size of each category is a hint as to how many pages are in that category.
