Are you active or former US Military? If not you'll need to get a sponsor in order to get full membership. We're a non-profit organization dedicated to US Military veterans, but we do allow friends and family as well as foreign allies and those who want to game with us, but you'll need a sponsor if you're not military.
Perfect, then head on over to MilitaryGamers.com and register there. I'll get your account set up and you can use the link on top of the forums there to get into TeamSpeak 3.
We're located in 979 just north of Founder's Isle.
