Alacrity Paintchat

I've noticed that, besides site artists, there are a lot of artists that use Alacrity. I think that everyone would have a lot of fun with a paintchat. :D One with opacity variation would be ace. Also, while it would be great for everyone to use, it'd probably be best to restrict use to upgraded users. This would minimize paintchat trolling; it'd be pretty easy to sign up just to draw naughties all over the paintchat.
