That thread has apparently been deleted. I could not find it either when I tried last week.
As far as getting past the registration question, the answer appears to be ” both “.
I sent an email to the admin about that stupid system, suggesting that the registration section be listed as “gimmickrally.com” instead of roadraceautocross. Never got a reply Come to think of it, I’m not sure that I am yet registered for the site, I did not get a confirmation, and I have not been back to try logging on.
From what I can gather, some changes in procedures and tech, and allowable devices may be in the pipeline. We will all be paying attention.
