We have a publicly accessible Discord server. This contains some general chat channels as well as a #survival channel linked up to the in-game Survival chat. When you chat from Discord, all messages have the prefix (Discord) applied before they are relayed to in-game chat.
If you're in-game execute the command
/discord and click the link,
or if you're already in Discord simply connect to http://discord.gg/Dq4CjN7
