Last year I became a member of the National Bone Marrow Donor regiistry. Although I haven;t been called to donate yet, I am ready and willing when that call does come in. Normally there is a $52 tissue processing fee to join the registry, but starting June 8th resgistration is free. The free registration only comes once a year, so if you have ever considered joing the registry now is the time to do so. Free registration ends at 46,000 new donors or on June 22nd, whichever comes first.
