Friday evening, I drove over to Wash U and got registered and swabbed! I've obviously been meaning to do this for awhile - but a colleague and I discussed it recently and it renewed my interest in attending a drive. Luckily, there were about 7 in the next month or so - but Friday's was the most convenient - both time-wise and locational-wise.
It only took a few minutes and a lot of paperwork - but now I'm officially registered and hope that I match someone in need.
I am looking forward to getting that phone call or email some day! I'll keep you posted!
