so i'm running our first its tourney in philly next month, and im trying to make sure i have a handle on the system. 1: how do players sign up for the event? do i have to find them and add them? 2: what does subscribing to an event do? 3: when people show up day of, and don't have its profiles, do i have to wait for them to make profiles so i can add them to the event? 4: the old forums had a place to advertise events; i feel that since this is philadelphia's (6th largest city in the states, you prolly have heard of it) first ITS event, i should prolly advertise it here, but can't seem to figure out where. Is there a proper place to do so? thanks in advance for answers!
