Free TeamSpeak Server

TeamSpeak 4 Free claims to have free TeamSpeak servers available for guilds etc to use. I haven't look into it. I play WoW, but given what I hear on channels, I have no wish to listen to people on TeamSpeak shudder. You might find it useful though.

Ventrilo is meant to be a nicer system to use than TeamSpeak. See here for free Ventrilo Server information
