Naming conventions

:See also: Wikipedia:Category names

Names and descriptions of user categories are subject to the same rules and restrictions as userbox content.
The name of a category should be clear about its scope and purpose and should generally follow the naming convention of fellow members of a parent category. See :Category:Wikipedians by interest for an example.
A user category should have an indication it is a user category. "Indications" include, but are not limited to: "Wikipedians", "WikiProject", or a name of a Wikipedia-specific organization or grouping. For example, :Category:Wikipedian mathematicians, not :Category:Mathematicians. Babel-specific user categories are an exception to this, and instead should follow that convention by having the same name as the Babel-specific userbox, i.e. Category:User (language code)[(-level)]. A category that complies with this point is :Category:User ar-3, for level-3 speakers of Arabic.
If in the userbox content, the verb (see Wikipedia:Userboxes#Content) is one of preference (enjoys, likes, loves, etc.), replace it with a more specific verb when selecting the category name. For example, "This user enjoys J. R. R. Tolkien" could be categorised as :Category:Wikipedians who read J. R. R. Tolkien.

Categorization

:See also: :Category:Wikipedians (category tree)

User categories must be subcategories of :Category:Wikipedians.
User categories designated as container categories should contain only subcategories and possibly a limited number of directly related pages. Individual users should not be in parent categories.
User pages and user categories do not belong in mainspace categories such as :Category:Living people or :Category:Biologists, which are reserved for articles of the encyclopedia (in mainspace). This applies also to user subpages that are draft versions of articles.

Syntax for including a user category in a userbox

{{see also|Help:Category#Putting pages into categories|Wikipedia:Userboxes}}

:REMEMBER: Userboxes should NOT automatically include categories by default.

The following example is from {{tl|User WikiProject Film}}:


{{userbox
| id = File:Video-x-generic.svg
| id-c = #FFFFFF
| info = This user {{#ifeq:{{lc:{{{1|}}}}}|coordinator|is a coordinator|is a member}} of
WikiProject Film.
| info-c = #C0C0C0
| info-a = center
| usercategory = WikiProject Film participants
| nocat = {{{nocat|}}}
}}{{documentation}}

<includeonly> and <noinclude> should be on the same line as the closing parentheses (}}) to prevent extra spacing from appearing when grouping userboxes on userpages.
Enclosing a category in <includeonly> tags will only categorise pages on which the userbox is transcluded. To show the userbox in that category, use {{tlx|User category}} or {{Your userbox name|nocat=}}. Remember to set the sort key as {{PAGENAME}}.
Enclosing a category in <noinclude> tags will only categorise the userbox.
