From Test-Scratch-Wiki

editlockedpages is a special usergroup that allows users to edit pages that are protected at the "editlockedpages" level. Some pages maintained by the Scratch Team are protected at the editlockedpages level.

Protection

There are different protection levels on the Scratch Wiki, each can protect the page from being edited, or moved. Examples of protection levels are 'sysops', where only sysops can edit the page, and another protection level is 'autoconfirmed', where only autoconfirmed users can edit the page. However, there is another protection level called "editlockedpages". These pages allow the usergroup "editlockedpages" to edit the pages. The editlockedpages protection is used for pages maintained by the Scratch Team. See Help:Group rights for more information on different rights and users.
