I've signed up for a 15 user TeamSpeak 3 server for us to use, details
are as follows:
Server: 216.6.228.98
Port: 10024
You can download the TS3 client for various OS's at
http://www.teamspeak.com. I'm personally running the client on my
Fedora 15 notebook and it seems to be vastly improved over the TS2
client, excellent support for audio and push to talk key from any app.
