So added a mumble server
You can download mumble here...
http://mumble.sourceforge.net/Get version 1.2.3 (though latest should work aswel)
Once you have installed it, run it, then goto [Server]>[Connect] Or just [ctrl]+[ o]
[Add New...]
Enter details like so...
server address: kraftzone.tk
port: 64738 (default)
And your minecraft username
Connect to it, you are free to speak and message, will be setting up proper kraftzone member channels later.
Mainly just using this for text chat, for those who want to chat while server is down.
