As a mentor for a team in the Los Angeles area, it is frustrating trying to register for my "home" regional that fills up in seconds. Especially when you see after that teams from out of state with low-fill-rate regionals registered there as a first event.
Just a gripe. I've never failed to get into my first choice event.
As for the bots thing, the registration process is written with the intent of a lead contact doing the work, not a program.
Read the instructions.
Says "Make sure you refresh your page at Noon Eastern on Thursday, September 22, 2016 in order for the Events to become available to your Team!"
Not "program a bot to do these steps for you hundreds of times per second."
