i want to know what to use and do you guys got any servers i can join

I personally use TeamSpeak. It is fine if you like to use a mic. But you can text also. It is more friend like for communication. The other is one I have not heard of so I wouldn't be first to go for it. Idk how to make a server but you ca. Join a server anywhere for free. Look for teamspeak on YouTube if you want to use it like a pro

I've heard 'mumble' is very good, worth googling.

I use teamspeak 3, I find it better than vent

Mumble is by far the best. I use it always.
Changed to it after Ventrilo stopped working with Win7, and I immediately found out that it had a smaller lag and a better sound quality.
And it doesn't even generate any game lag, even with my 1MB/512KB connection.
It's simply the best.

My team uses TeamSpeak 3 in the office.

We have an open server if you would like to join: warservers.net:9987

That is UK server if you want a US me and Ben are sorting out a AOS TS3 server.

ok ill check them out

neither, Mumble is much better than both.

feel free to use this Mumble server, located in Fremont, California, USA:

address: mumble.aloha.pk
port: 36025

or copy & paste to connect:

mumble://mumble.aloha.pk:36025?version=1.2.3
