Ok i setup a mumble server (its actually called murmur on the server)
mumble is a free VOIP software similar to teamspeak or ventrilo, but its free, more configurable, lower latency, lower bandwidth and open source, and free to host
and it works on every platform.. so basically it dominates all other gaming voip servers
you can get it here:
http://mumble.sourceforge.net/the information to connect to the one hosted by me is:
Server: SoulFire (you can name it anything actually)
Address: soulfire.cc
port: 64738
name: whatever name you use
later on i will tie the website and server to use the same user database, but it doesnt yet
im also planning on updating the sites software and look for starcraft 2
