6 locos: pick real courts (spots = 4 × courts), mode, optional category
limits. Rosters can be open (players join) or filled by you, including
guests by name. Rounds are generated automatically per mode, and
round 1 only becomes available 30 minutes before the start — generating
it freezes the roster, so nobody can join or leave afterwards.
Clinics: pick one of your coaches, a court, duration and capacity
(up to 6). Players enroll or you add them; there's a waitlist when full.
