It's a prize draw competition which you can enter by signing up to the Dynamics Community.
To join the fun, first visit: http://community.dynamics.com/ and sign in with your Windows Live ID. Then visit http://cashinwithdynamics.com/ to where you can spin the wheel to get points. The grand prize is a Vegas trip with all inclusive, but check out the site there is a lot of other prices.
Extra points can be gained when someone joins the community and your screen name is entered. Btw. My screen name is “Soren Nielsen”.
