How to be a bone marrow donor

From my brother's Facebook:

Kristn needs a donor and so do thousands of others. Easy to join and easy to donate bone marrow if needed.

I can't donate because I'm a Stage 1 breast cancer survivor, but thought I'd post it here in case anyone is looking for a good deed to do.
