Hi, newbie to the forums here. I'm still waiting for my Google+ invite but I'm eager to give it a try. As for making invite registrations work, I've heard some people say that they were able to get their invites to work after a few tries at trying to register.

BTW, in case anyone has a private Google profile, Google will be doing away with private profiles by the end of this month (July). All Google profiles will now be public, which means the account holder's full name and gender at a minimum will be publicly available. I guess this is preparation for opening up Google+ to everyone.
