This category is a meta-category for listing "tracking categories," categories that are used to build and maintain lists of pages to aid in wiki maintenance. Tracking categories should be hidden by design. Only categories should be added to this category - articles should not be added here.
See also Special:TrackingCategories for a server-generated list of tracking categories used by the MediaWiki software automatically.
