After reading the previous messages, I figured, what the hell, I'll try it. I clicked the Purchase tab. It displayed a list of races. I clicked the USAC box. It displayed an ad. Up in the corner was a Register tab, so I clicked it. That looked promising, so I filled in the blanks. It displayed a dialog that said my username was already taken (my email address?). Before I could do anything, it displayed another one that said I was registered.

But, I can't log in. I just got an email that it has charged my credit card. I'll contact the bank to cancel it in the morning. Isn't it amazing that part of the web page worked?
