Find your people at a festival. Tag the sets, see where everyone is, rate what you heard.
You're in your crew.
One person sets it up for a festival, then invites everyone else with a link or a QR code.
You'll need the link or code, and the passcode they were given.
You'll be its admin — you can add other admins later.
Show this to anyone standing next to you:
The QR code carries this already. Share it separately if you send the link.
