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.

Pages in this category should be moved to subcategories where applicable. This category may require frequent maintenance to avoid becoming too large. It should directly contain very few, if any, pages and should mainly contain subcategories.

This category contains requests for images that are specifically drawn diagrams. It is formed on the grounds that there are a lot of articles that would benefit from diagrams, and diagrams are created by a process sufficiently different from other images. Charts and graphs, where possible, should be created with user-editable templates such as those in Category:Chart, diagram and graph templates and Help:Graph.

This category is populated by the template {{diagram requested}}, which creates a banner suitable for inclusion at the top of a talk page. Please use a more specific media request template as appropriate. For logos, use {{logo requested}}.
