Rollback privileges allow a user to undo multiple edits by the same user in quick succession. If a user has made a chain of edits to one article that are all vandalism, Rollback users can revert all of these edits in just one click. Rollback is designed to help users combat vandalism, and should not be used to edit war. No edit summaries can be made, and the edit will be marked as a minor edit, so be careful what you revert! Rollback users have no special authority over other users.
