To join the Discord server, simply use the link below or click "Connect" in any of the Discord boxes on the wiki.
You don't need to create an account to join the Discord server to start with, you can just assign yourself a username and join the chat. You will need to provide Discord with an email and password if you wish to retain access to your provisionary account, though. Most of the time, there's someone there to talk about everything Edge-related. See you in there!
