This is an administrative category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories (except for eponymous maintenance categories).

This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme.

• This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
• These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
• These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.

This category is used to track {{Language with name/for}} template errors. This category is used only by Module:Language with name/for.

Module:Language with name/for consolidates the processing of {{Language with name/for}}. As part of that, the module emits error messages when the template parameters are used inappropriately or when the data assigned to the parameters is malformed. The error messages are:

• missing language tag or language name – this template requires one of positional parameter 1 ({{{1}}}) or |lang-name=. To resolve this error, provide an appropriate language tag in {{{1}}} or an appropriate language name in |lang-name=. See template documentation for specific requirements for these parameters.
• only one of {{{1}}} and |lang-name= allowed – because a template with both of positional parameter 1 ({{{1}}}) and |lang-name= may be conflicting, only one of these is allowed; use the most appropriate. See template documentation for specific requirements for these parameters.
• missing English translation – an English-language translation in {{{3}}} or |term1= of the non-English text is required. To resolve this error, provide an appropriate translation.
