There are plenty of mods at the moment, though I'm sure Jordan already has his eye on portential additions. Right now we have a pretty good spread of time zones, as well, so that someone is on at most times around the clock.
Two things you can do to help: use the 'Report to Moderators' button on unacceptable posts, and be specific in the comment you add. Sometimes it's obvious what the problem is, sometimes not. But that button really does help us put our attention in the right place.
The second thing is to post calmly to users with bad behaviour, and tell them that they're violating the rules. Don't attack and start a flame war; just say "Look, that's not appropriate, and please knock it off." It's amazing how many people will go away on their own if they can't get a rise out of their targets.
