A user category is a type of category—a grouping of related pages[] intended as a tool for navigation[]—that contains the user pages of Wikipedia users. The technical function of a user category, therefore, is to group the user pages of Wikipedia users who share one or more characteristics. Given this technical function, and considering the principle that Wikipedia is an encyclopedia and not a social networking site[] or personal webhost,[] the purpose of user categories is to aid in facilitating coordination and collaboration between users for the improvement and development of the encyclopedia.

In addition (similar to all categories[][]), user categories should not be used as "bottom-of-the-page" notices.[] If a Wikipedian wishes to have such a notice, they may edit their user page and add the notice in some other way (such as by adding text or a userbox), rather than inappropriately creating a category grouping.[]
