The pages in this category are redirects from empty categories that have the possibility to become working categories with entries. To add a redirect to this category, place ((R category with possibilities)) on the second new line (skip a line) after ((Category redirect|(target category title))). For more information follow the links. Never substitute redirect template(s). See also the complete list of redirect templates and the redirect style guide.

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 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).

This category contains category redirects that potentially could be populated as separate categories. These redirects appear here as subcategories rather than as ordinary page entries. Category redirects are placed in this category by adding ((R category with possibilities)) on the second new line after ((Category redirect|(target category title))).

Other pages should not populate these redirected categories. If you find category links to these redirects from articles/ templates/ categories/ portals, please do retarget those links directly to the category page to which these entries redirect.
