Rollbacker

A rollbacker is the concept and term used for a user who has the on-wiki ability to collectively undo a number of edits by one editor (on the same article) with a single click. On smaller wikis with limited numbers of staff and / or editors, this facility is generally included in those granted sysop rights; whereas on larger wikis such as Wikipedia, rollback rights may be as a result of regular users, who are hopefully trustworthy, being given an extra privilege, and therefore a new separate user group.
