The GMOD web site makes extensive use of category tags to flag pages as being related to various topics. Category tags give users an alternative way to navigate the web site, and editors are encouraged to add tags when they create or modify pages. We strive for each page have at least one category tag.
Category tags are shown here in two formats:
There is also a list of pages without any category tags.
Category Tag Cloud
The category tags used in this web site are shown here as a tag cloud. The font size of each category is a hint as to how many pages are in that category.
Alphabetical List of Categories
Eventually this section will list the categories in a tree format. It doesn't do that now because the extensions I can find that do this (CategoryTree and NiceCategoryList2) require the creation of a single root category which all other top level categories are made subcategories of. This strikes me as too much maintenance.
If you have any suggestions on how to display categories in a tree format, please send them to the GMOD Help Desk.
