If anyone has Mumble, which is like Ventrilo or TeamSpeak but better, they can join the Mumble server we have set up: [monospace]zoomcat.no-ip.org[/monospace]. If prompted for a password, enter [monospace]viper[/monospace].
The server is shared with some of my friends in DayZ and L4D2, so don't be alarmed if you see unfamiliar faces.
