How do I check in at the venue on the day?

When the organiser opens check-in, you'll get a message. Once you're at the venue, open the competition's page and press Check in. The organiser can also tick you off at the door.

Don't be late. Before the first round, the organiser can give your place to someone on the waitlist who's there. And when the organiser pairs everyone up, anyone who hasn't checked in is taken off the list.
