We used to have an IRC channel, like 2 or 3 years ago, but not anymore. We've been using the shoutbox and IM for all our live text communication for awhile.
I've sort of been offering my voice chat services but nobody really cares. I had a couple TeamSpeak servers between around 2003 and July of last year, at which time I switched to
Mumble which is more similar to Ventrilo but better (IMO). theONE has been joining every once in awhile, particularly because he helped co-host a podcast I was doing, but other than him nobody else from TDS joins the server.
