So Usherr knows who you are in your Discord server: type /link there, and the six numbers it gives you here.
In Broadcast: You, Your settings, Linked services.
In Classic or Neu: Settings, Account & Access, Linked services.
In the Discord server Usherr posts in, type /link in any channel, choose Usherr’s /link from the list and press Enter. The bot answers with six numbers. Only you see them, and they work for 10 minutes.
Under You, Your settings (in Classic or Neu: Settings, Account & Access).
Type the six numbers and press Link. Your Discord name shows here once it’s linked. Linking posts nothing: only what you choose to share is ever posted.
Usherr now knows your Discord name. Unlink any time on the same card.
