How to download WPMUdev on site to download themes?

Hi Guys, thanks for all your help with The contest went so well and I have you to thank for that.

I am starting a site for the actual book now. Can you please remind me how to import WPMUdev on my wordpress site so I can download a theme? I didn't go with any of your themes for the last site but I'd like to explore what new ones may have come out since then. Thanks! :slight_smile:
