I could easily buy a 15 slot vent server but I've stumbled across something else magnificent. It's called GSC and it's like Vent, Teamspeak, and xfire Combined. The best thing about it is.. Its Free! I believe that we will fall in love with GSC if we just give it a try. And if we don't, we can always pay for another vent server.. Some of the GSC features include :
Free Voice Communication

* Create multiple channels and subchannels
* Pick from any of our 12 datacenters worldwide to host your voice server
* Full moderation of your voice channel, including the ability to kick/ban users
