Dear Byfield,
It is wonderful that you are interested in registering to become a bone marrow donor! There is a definite need for generous people like you. I would recommend you visit the National Marrow Donor Program website at www.marrow.org. There is a lot of information on what it means and how to become a bone marrow donor (to search for local marrow drives that you can attend or to find a local recruitment office).
Thank you very much.
