Our official chat app is Mumble, an open source, low-latency, high quality voice program primarily intended for use while gaming. We maintain our own Mumble server 24/7 for guild members. Many games provide a built-in voice chat system, but they are often not reliable enough to use in all situations, and we may not always be playing the same game. Windows, macOS, mobile, and Linux apps are available.
To the left is a live display of our Mumble server, and who currently is online. Guild members are welcome to join in at any time. To get your login information in WoW, open the Guild Window and go to the Info tab on the bottom right.
