This is a maintenance 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. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (appearance → show hidden categories) is set.

This category contains pages which have been semi-protected from editing indefinitely. Semi-protection prevents anonymous and newly registered users from editing; contributing accounts must be at least 4 days old and must have made at least 10 edits to non-protected pages (including deleted ones).

Use {{ Pp-semi-indef}} to add pages to this category. This should only be done if the page is in fact semi-protected – adding the template does not in itself protect the page.
