Category:Help namespace categories
 | 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 container category. Due to its scope, it should only contain subcategories. |
Description: Contains categories whose members should only be in the Help namespace.
This Petscan query can be used to check for any pages in other namespaces.
