Virtual Rush is back -- with more features, more prizes, and an even cooler Grand Prize. Here's what it's about: Every week, we give you a new challenge to create and post your own clips (or pix) on a topic. This week, you can Invent Your Own Superhero!

Yo, it's week four of 'Rush'd' -- and it's 'The Moment of Truth!' Watch all week as the finalists tour the 'Greek' set, meet the show's producers, and hang with the actors who play Cappie, Ashleigh, Rebecca, Calvin, and others.

Friday, watch as the contestants make their final appeals, because voting starts next week! If you're a registered Virtual Rushee, you'll get three votes per day all week (11/19-23). Cast 'em any way you want -- all for one or split among your faves.
