Any idea how long the signup page is down? I made my account yesterday and, when forced between using my google auth and making some pokemon.com account, it was a no brainer to not use my google account. It took me a few tries but since this is a game and not something in the realm of life-and-death, I found it wasn't horrible to actually wait. And try again.

The entire issue is predicated on using your google account credentials which isn't really mandatory. Maybe I'm overly cautious but I don't use my google account to auth anywhere. If that's the only option, and it's not a google product.. then it looks like I'm not using that service.
