Took you a while to find that page, eh?
It was found a few days after gmail was announced. That page only allows you to make a Google Accounts account. Which gives you access to all public services, not a private service that's in testing, like Orkut or Gmail
At least this isn't one of those, I have invites, i'm willing to give them out if... threads, god I hate those.
Edit: Demandred, please don't bloody quote a whole post, just to type a small reply that could have been said without quoting >_< and on top of that, it's the first post in the thread..quoting prevents confusion. By quoting the first post in a thread, you've created confusion, good job
