Space (in bytes) that a user's total attachment usage may consume (Set to 0 to not have a limit)
We can limit this.
I think we'd be fine setting this limit (in the user group). We turn it off for moderators, we set a limit for registered users.
But I think we'll need an extra usergroup to be created. In the event I kick Marvin's ass to the curb

over the hot-ha stuff ... we'd lose those how-to's. So I think we need like... a retired moderator group? We already have a few of those, we might as well deal w/it.
Which leads me into wondering what this 'promotion' stuff is dealing w/the userbase... I'll look into that.
