Returning user more likely to click Sign Up than Log In

Every time a returning user goes to when not
logged in they see:

Get Started Today    [email protected]     **********    Sign Up

already filled in by the browser, so naturally he will accidentally
click that Sign Up instead of the correct Log In up in the right corner.

You see all other sites have Log In already filled out like that,
and Sign Up in a small link below it.
