This is amaintenancecategory, used formaintenance of the Wikipedia project. It is not part of the encyclopedia and containsnon-article pages, or groups articles by status rather than subject. Do not include this category in content categories (except foreponymous maintenance categories).

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

• This category ishidden on itsmember pages—unless the correspondinguser preference (Appearance → Show hidden categories) is set.
• These categories can be used to track, build and organize lists of pages needing "attentionen 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).

To add a page to this category, use{{Pp-pc}}. This should only be done if the page is indeed protected; adding the template does not in itself protect the page.

For a dynamic list of all pages under pending-changes protection, seeSpecial:StablePages. For a dynamic and sortable list of all protected pages, seeSpecial:ProtectedPages. For reports of protected pages, seeWikipedia:Database reports#Protections.
