if you go onto the history page of almost any page, you'll see the button that says "Rollback". If a vandal comes onto the wiki and makes a lot of bad edits, then you can press that button and all their edits will be changed back. That's mainly what they do. But around here you'll be helping out with planning events, attending meetings, helping keep the wiki calm, etc. etc.

You can't block people, or delete pages, though.
