Overall, it looks and works fantastic.

I would adjust how tapping the Log Out button works. Instead of transitioning to a new screen with simply username and password fields present, I suggest replacing the upper part of the UI with the login fields and leaving the other elements at the bottom of the screen there. It would be more seamless, and would provide access to the news, forum, and rules links. You could remove the email and log out links and leave a "Logged Out" display on the left.

that login screen is actually temporary. when the game releases the login flow will be completely different, since we won't have a pre-registration process like we do now.
