Love the registration/login flexibility.

My company still hasn't implemented FastPass because only half our current customers use our Account/Membership system. I've had mixed feelings about this, but my comfort level with using Get Satisfaction accounts for now has soared immeasurably with the knowledge that our users are presented with so many other options for using existing accounts. The interface is really lovely as well. Nice job!

One small suggestion is to link to the many registration options from the "Sign Up" link, not solely from the "Log In" link. (on the toolbar)
