There are two groups with similar objectives on FaceBook. One is ¨Living Donors on Line¨, and the other is ¨Living Kidney Donors¨ (which excludes liver, lung, etc. donors). They often overlap, as some donors post on both pages. I've been on them a while, so don't understand why you are having difficulties. There is also a FaceBook page for "Kidney Donors With Complications". All I can suggest is that you keep trying. I'm not much good at computers myself.
