React to check-in
When the tournament organiser opens check-ins, you'll see a message posted in #tournament-info.
To check-in, simply react to the message!
Regular vs. captain-only check-ins
Whether your team is considered fully checked-in with a secured slot in the tournament will depend on the tournament settings:
Regular check-ins: All players on your team must check-in.
Captain-only check-ins: Only the captain needs to check-in.
Checking in when you're on the wait list
If your team registered after all slots in the tournament were filled, your team will be considered on the wait list.
If you're on the wait list, you should still check-in. If any registered teams fail to check-in, your team will automatically replace them in the teams line-up when the organiser closes check-ins.
