I just registered today! I'm really looking forward to this and other events as I've not yet participated in anything other than the Main Arenas. It took awhile to find the appropriate locations to "register" and obtain timing information. Once I registered to the ACES HIGH Events page, I was able to find out more information about each event.
I registered for the Hurricanes as the spits were filled up already. Unfortunately I will be unable attend the first frame..
At any rate, I look forward to participating!
