I think I finally understood the game, I thought I could register today but just checked the website and saw the details. You have to register during the 1 hour session, and for tomorrow that is at 7pm I guess Europe time,,, which is sleep time for me. Is there a way you could have a few sessions in another timezone? If not it is fine:)
The registration opens 30 minutes before the scheduled game. The countdown timer indicates the registration open time. For now we also have Saturday sessions (morning EST) that might suit your TZ better. If we can get the game to start paying for itself we will definitely work on getting some additional games going to make it more convenient.
We actually have players that stay up or set alarms to participate
