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 and its subcategories contain project pages which have been semi-protected in line with the protection policy. Semi-protection prevents a page from being edited by anonymous and newly registered users. For fully protected pages, which can be edited only by administrators, see Category:Wikipedia protected pages.

To add a page to this category, use {{ pp-semi-protected}}. This should only be done if the page is in fact semi-protected.

Note that adding the template does not in itself protect the page. Conversely, protecting the page does not automatically add the template (or any other visible protected-page category linkages), which results in some pages having a "view source"-tab instead of "edit this page" and yet not showing "Semi-protected" at the bottom -- a situation new users may find rather confusing. Therefore, it is best to always add the template immediately after protecting the page.
