It appears that the NMDP is not making this easy...I contacted them to inform them of the difficulties and to ask if they could make it easier. For now, follow the directions below, and, hopefully, you'll be able to register for free.
Go to www.marrow.org
On the right side of the screen, under "Events" click on the link that says "NASCAR Foundation Drive"
About 3/4 of the way down that page, click "Join online now"

Beyond organ and tissue donation, another huge need is bone marrow donors. Fortunately, you don't have to be dead to donate bone marrow, but you do need to be registered and tested. Over 6000 people are currently searching for a bone marrow match.
Through September 22, the National Marrow Donor Program is waving the normal fees for registration (usually about $50).
Because we have a family member who may need a bone marrow donor at some point, this is something that we are very passionate about. Please, consider Registering Today!
