First, download the Client for your OS from here:
http://www.goteamspeak.com/?page=downloads
(The 5.59 MB one if you’re on windows, the 7.18 MB one if you’re on linux but if you’re on ubuntu teamspeak is in the package manager so you can just go to add/remove programs)
Once downloaded and installed, start it up.
The procedure to connect to the server is this:
Connection -> Connect
Label: CUSEC
Server Address: 216.99.51.131
(Be careful to not put any spaces it’s picky about that)
Nickname: Your name
Anonymous
Server Password: cusec
Default channel: cusec
Default subchannel: cusec2
Channel Password: cusec
I also suggest you change from voice activated talking to “push to talk” mode.
To do this, go to Settings->Sound Input/Output Settings
Select Push to talk
Click Set
Press any key on your keyboard
Click close
From then on, only when you’re pressing that key (no matter what app you’re using so pick something weird like F12) will your mic be activated.
Also, we’re chatting on irc on the freenode network. We’re in #cusec so either connect there with your favorite irc client or if you don’t want/have an irc client you can connect through www.mibbit.com
