Before you do anything you should Register your Mumble, be sure to be using the name that you most commonly associate yourself with.
We're using Mumble for voice communications. For organization, each team will have three channels, one for builders, one for attackers, and one for defenders.
You'll have one button to communicate with the people in your squad, and one button to communicate with your team.
Squad communications will work like normal, but for team communication you'll have to add a setting.
Keep full-team voice chat to a minumum, as you don't know if you're interrupting anyone.
For unimportant messages, use ingame team chat.
Remember for all you noobs, "T" for general chat and "Y" for team chat
