Rollbacker

On a MediaWiki-powered wiki site, a rollbacker is the wiki concept, term, and user group used for a user who has the on-wiki ability to collectively revert or '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 an extra privilege granted to regular users, who are hopefully trustworthy, therefore resulting in a separate user group of rollbackers existing.
