I just wanted to pass along that I was able to successfully register!  There are always community members out there who manage to find a way out of no way.  I want to point out that although it worked for me, it many not necessarily work for you.  I still encourage everyone to sit back and wait for the initial site to be ironed out.  (Deacon’s a bad boy)

As you can see, I am a member since 2/14/2007 so it did work.  I want to give credit to the people behind the design of the site.  It looks great!  They’ve even managed to implement the program into a jazzy, new Gamercard for participants to show off as they travel message boards etc.

As you can see, I have yet to complete any challenges but as I do, they will appear much like your games played appear on the regular Gamercard.  Your Level is indicated by the highlighted Xbox 360 controllers.  Currently, I’m Level 2.  The site will keep track of all your trophies (completed Challenges) and also keep track of how many points you need to ascend to the next Level.  It’s really amazing once you’re signed up.  Anyway, on to the way I was able to register. 

Click this link https://xboxrewards.msgamestudios.com/myRewards/Rewards.aspx and you should be taken to the Xbox Rewards page where you simply click ‘Sign In’.  From there, it’s pretty much a ‘follow the prompt’ type of thing.  Verify your information, click ‘Agree’ and you’re in.  There are still some bugs in the site but at least you’ll be in.

*edit - I’ve been able to navigate the entire site so it appears as if the bugs have been worked out.  Head over to www.xbox.com/rewards to get your registration on.  Happy, happy…joy…joy.

Good luck.
