I tried Nextdoor too. A couple of people responded but did not follow up / through when I gave them transplant center contact info for living donation. Facebook was useless. Some people responded wanting to sell their kidneys! Others were creepy phishing inquiries. I even printed a bunch of postcards stating my need and the transplant center info. I asked for help spreading the word and put these cards inside my Christmas cards. A few relatives and former “friends” reacted badly to this. Sorry, now I’m just fussing when I started out wanting to encourage you.
