External: Mumble voice server!, Update by Dr. Cossack
A voice server is now available for all players! I know that many of you are using Skype to chat while playing, and I'm providing this as a more convenient alternative. The voice server is always available and doesn't need you to build a contact list and reach out to people separately, making it easier to get larger discussion groups going.
If you already know your way around Mumble, connect to 22.214.171.124:64963 and ask for the password in-game. For the details, view the voice chat page!
On another note, the Commands page has been replaced with Tips & Tricks. This new section includes more information about special server features and details the Home Protection Program, used to save your creations against unwanted modifications.
