A rollback is as Birdpaw says, and they're really useful when combating vandals. They're higher up on the ranking list then a chat mod, but, the don't have the kickban feature.

Regardless....if Night or I ever need a break, the Rollbacks are the ones we look to to keep an eye on the wiki while we're away...and if either of us leaves the wiki (I doubt it'll happen for a looooong time) one of them would surpass us and get admin rights.
