Ratsky does a great job as our official unofficial moderator for the chats, but there's no reason other people can't toss up tinychats or whatever if they want to chat outside the scheduled times. Like this:

Blam! Impromptu midday chat. I have, like, 20 minutes. Or maybe I'll liveblog palliative medicine...
Depression-GAF is super active on skype, too (text chat - not video), as well as Steam (but less so?). I'm on skype most evenings and I'm always happy to talk if things aren't nuts. That's a great place to meet some of the really active people from this thread.
I'm gaf.bagels on skype - feel free to add me, but if you do, for the love of God, tell me who you are on GAF in the invite you send (or, alternatively, just say you're from GAF). I'm bad with names, and many people are different on GAF, skype, AND Steam. Every time I see poor Windam I have to ask if he is who I think he is. It's a neurological disorder I'm trying to get named after myself.
People on skype are sort of silly, serious, heart-breaking - sometimes all at once. It's a good place to vent or ask for advice or just goof around.
