Sounds like you've used TS before.

I admit I've been new to Teamspeak 3 and only really tried it when ATAG began using it recently. It was easy even for All-Thumbs Snapper to get up and running. What really knocked me out was the clarity of the voices and the apparent absence of "satellite lag" - critical if someone is telling you to "Break left.......NOW" when you have a 109 on your tail. I quickly learned to assign a joystick button for "push to talk" since that is also the precisely wrong time to be fumbling for a keyboard setting! LOL

Further to that, I've gotten all kinds of useful tips through casual conversations on TS during the quieter moments of a mission (advice on ammo belt load outs, CEM settings, etc etc) that would not likely be typed out in a chat box. As you indicate in your post above, Teamspeak really adds to the experience if you have a cheap headset with a microphone. And it's freaking FREE!!

I also had a very pleasant experience in the ATAG server. Nicely setup and smooth connection.
Thank you Guys :)
