For a long time, I've wanted to sign up to be a bone marrow donor. Unfortunately, in the past, they've expected the potential donor to pay for all of the tissue typing tests. I've not wanted to have to pay for that, so never bothered joining.
However, for a short time, they are waiving the fee for the first 10,000 people to sign up for the list. So, I signed up tonight.
