Just a reminder on how to play PR3 when sparkworkz doesn't load levels anymore.
Log in to PR3 as yourself.
Open up another tab, go to sparkworkz.com, and log out.
Go back to your original tab, and levels will load right away for you. Downside is you don't keep any hats/parts you win, and next time you come back to PR3, you will have to log in again.
