Recently, I found a few abandoned profiles that seem to be project-protected, like the father of our king, Claus von Amsberg, and his grandfather, Bernhard von Lippe Biesterfeld. I adopted them, and was somewhat suprised to see that I could actually do that, since I don't remember actually joining any special project yet.
Hence the question: Is there a protocol for this? I adopted these, because I share some ancestors with some of them, but I don't really have much knowledge about European royalty yet.
