I was going to join this a while ago but never figured how to get onto it, and noticed a lack of headphone&mic
It's ridiculously easy, all you do is download the http://teamspeak.com/?page=teamspeak3, write in the s
erver name (ts82.light-speed.com:8841) and hit connect.

Headphone/mic lack might be a problem, but there are(/were) some people that joined, even though they didn't have mics, and they kept up with the conversation just fine, AFAIK.
