All categories together form a plan to bring structure to the content of the wiki. If a user has an idea for a new category or category type, they are to contact an admin to create one, though preferably after they've thought about the ways the new category or categories would affect the current organization. Users who have extensive knowledge of categories and a clear vision on the proposed new category or categories may create them on their own, but asking permission and/or feedback beforehand is STRONGLY recommended. The same rules apply to editing existing categories, with the added note that vandalism of categories results in a ban.
