Category:Hidden categories

From The Blockheads Wiki

Hidden categories do not appear in the list of categories at the bottom of the page, unless the "Show hidden categories" preference is checked, which is not available to readers.

A category is marked as hidden by putting the __HIDDENCAT__ magic word on the category page. It is automatically added to this category.

Maintenance categories, especially those that contain articles, should generally be here as they're only useful to editors.
