What is a "poweruser"? I've looked at a few wikis' user lists, and there are a few, but I'm not sure I really understand it. Is it who's active more often, kind of like on a forum community, where someone is on a lot and... well, that's a really bad analogy. I can't find it anywhere in the Community Central search.
