SkyTemple:Maintainers

Maintainers are trusted users that are given the ability to edit some protected pages, as well as a couple extra permissions.

Maintainers help keeping articles up-to-date, including curated articles. They can also review edits by regular users and mark them as patrolled.

On top of the permissions granted to autoconfirmed users, maintainers can:

Edit maintainer-protected pages (the current list of maintainer-protected pages can be found here)
Move pages without leaving a redirect
Quickly rolling back multiple edits from the same user on the same page
Mark edits as patrolled

This list is not exhaustive, for the full list of permissions for this and other groups, see here.
