Help:User access levels
Different users have access to different functions of the site. The creator of a wiki is automatically given administrator and bureaucrat rights.
Anyone, including users without a user account, can read the wiki as well as create new pages and edit unprotected pages. Any non-banned user is free to create a user account.
Logged in users
Users who have created an account and logged in (this is free and only requires a username and password) can change the title of a page by moving it. (That is much better and faster than creating a new page and moving the content.)
Logged-in users can upload an image or other file to the wiki. There are restrictions on which file types can be uploaded.
Logged-in users can mark a page on recent changes as "patrolled" to show other users that they have checked an edit.
Logged-in users can also customize the display of the wiki using Special:Preferences, as well as maintain a page watchlist.
Users with the "rollback" permission are able to revert vandalism and bad-faith edits by using the rollback link on diff pages and user contributions list. They are just like logged-in users, only with one extra button. They can be promoted via Special:UserRights by either an administrator or a bureaucrat.
- Main article: Croc Wiki:Administrators
Administrators can delete pages and page histories. They can also undelete a previously deleted pages and files or undelete specific revisions of it.
Administrators can lock (protect) a page so it cannot be edited or renamed by users without admin rights.
Administrators can block an IP address or user name from editing.
Administrators can revert bad edits more easily using a "rollback" link which appears on diff pages and user contributions lists.
Administrators can edit the MediaWiki namespace to make changes to the interface. However, CSS and JS style sheets (e.g. MediaWiki:Common.css) can only be edited by someone who has been promoted to an interface administrator.
More information can be found on the administrators' how-to guide.
A bureaucrat can make other users into bureaucrats or administrators using Special:UserRights by typing in the username and clicking the appropriate checkboxes. Alternatively, they can go to a specific user's contributions page, easily accessible from Special:RecentChanges by clicking the "contribs" link next to a user, and click the small "user rights management" link. Keep in mind that it is not possible to demote a bureaucrat once they have been promoted.
Some Miraheze staff members who are part a global group, such as stewards, are already given full administrative access to all Miraheze wikis.
