Other than logging into these forums? Does it link anywhere to our stats?

Beats me. I have created an account using the in-game form and dont know what to do with it in-game.

Exactly, I created this account via in-game, and when I click on the gamesas option, it just asks me if I want to create a gamesas account again.

Well, it's not that clear but i'm sure it will link stats eventually. Kind of similar as to how the Xbox Demo came out before the PS3 demo did. Eventually it has to be useful in some way. Otherwise Playstation is gonna be like "Wat da fudge? Why xbox get better stuff?" (My horrible interpretation of the Japenese Playstation Officials).. It's still questionable though..

Maybe ina a latter patch It will correctly lead to MyCrisis site and be able to access.

They have stated that Stats and whatnot will be linkable but to me it's an unfinished portion they shouldn't have even mentioned at all considering I doubt they'll make them linkable.

Yes, the stats will be placed on this site. Its just a beta at the moment.
Its been confirmed they are still working out the kinks before going live.
