Also, it's super easy to get on the registry. Just go to www.bethematch.org, and give them some information. If you qualify, they send you a kit and you send them back some cheek DNA.
Here's my kit, ready to send back.
It was easy too. Just swab the inside of your mouth, put a bar code label on the stick, and secure it in the foam bit. Then do the next one. It was kind of like a little craft project, and you all know how I love craft projects!
Go! Do it now! It's really such a small inconvenience to save someone's life. I hope I get a call.
