Making an account
There's nothing to sign up for. Log in with any new name and password, and that account is made on the spot. Keep the password: it's the only key.
"Invalid username or password"
- Names aren't case sensitive, but passwords are. Check Caps Lock.
- If someone else already has that name, pick another.
Forgot your password, or think someone else has it
There's no email recovery yet. Ask on Discord, in the support channel, from the Discord account you play with. Staff will ask what they need to confirm it's yours. They will never ask for your password.
Banned or muted
The message in the client says why. Appeals go through Discord.
