Teamspeak is a voice communication program to make control and gameplay easier and more smooth during raids(and save me gobs of typing) Having a microphone is not a requirement. having it installed so you can hear the raid leaders is.
Install and setup: download the newest release version for your nationality. install it to the location of your choice(c:\program files\ being the default directory)
Once installed, open the program via shortcut on your desktop, or Start>Programs>Teamspeak2 RC2>Teamspeak2 RC2
setup the connection to our server by click "connection" on the toolbar. Then select "connect" under the "servers" in the box on the left right-click the background and choose "new server" name it so you'll remember that it is the OwA Teamspeak server. Then fill in the sections as I describe below.
Server Address: 209.160.43.173:10036
Nickname: (enter your handle here)
Anonymous Login (to get a registered login request it from one of the server admins)
Auto-Reconnect (make sure it is checked so if you get dropped during a raid you won't have to tab out to reconnect)
Channel Password: (obtained via the guild MOTD or by officers of the guild)
