Protected Pages are just that: articles which have been protected to stop any editor who is not an Administrator from editing them. This is usually done to prevent vital pages and those with a high risk of being targeted by wiki vandals from being vandalized. The exact reasoning behind the article in question being locked will be displayed when a user attempts to edit the page, and the article's talk page may provide additional information on the subject.
If need be, it can be requested on the talk page that the article be unlocked in order to make changes. However, because an administrator can edit protected pages, an administrator may make the change instead of unlocking the page to prevent problems.
- An Unprotected page allows all users who have an account to edit. Pages with this level of protection may also usually be moved by any user.
- AutoConfirmed Users Only protected pages prevents the newest members from editing a page; also see Help:Group Rights#Autoconfirmed Users.
- Administrators Only is the highest level of protection. This prevents anyone from editing or moving a page unless they have Administrator/Bureaucrat privileges enabled.
(Note that the above levels of protection may be applied independently to editing and moving rights; e.g. an article that can be edited by all users may not always be moveable by them.)
