We are no longer going to be using Mumble for VoIP communications. I've setup a TeamSpeak 3 server for us to use now. I don't know how many of you are familiar with it, but it's not hard at all.
Simply download the TeamSpeak 3 Client for your particular operating system. Go thorough the automated setup process. Add a new "Bookmark". And use the address "boocraft.net" to connect to. Simple as that. No long address and port number to deal with, just plain old "boocraft.net" for the address. Connect and enjoy.
(no port, no password, everyone welcome)
Oh and anyone can create their own temporary channel. When you create your own channel, you will become the channel admin and have permissions to kick people from your channel. You can even password protect it as well if you just want to talk with specific people. Add people to your friends list and send offline messages. Lots of features to play with. Have fun!
