This is a WikiProject, an area for focused collaboration among Wikipedians. New participants are welcome; please feel free to participate!

WikiProject Categories has been set up to help manage the categories of Wikipedia and improve them. The goal is to categorize all articles in a way that is consistent with the guidelines at Wikipedia:Categorization.

Discussions about categorization policy happen at Wikipedia talk:Categorization. That page is also the place for solving specific issues related to category organization.

To discuss deleting, merging, or renaming categories, see Wikipedia:Categories for discussion.

Please direct all talk to Wikipedia talk:WikiProject Categories if you would like to help or comment on the project.

There is a task force that puts uncategorized articles into categories.

You may wish to view all subpages of this page.
