For those of us working on the ancestry of adoptees, we now have a long-overdue Adoption Portal to use as a gathering place:
http://www.geni.com/projects/Adoption-Portal/24449
If you are looking for help with a line, learning how to research adoptees, and/or are interested in advocating for adoption integration on Geni (including the development of consensus-based display standards), please come help get things rolling!
And of course, if you have profiles for adoptees, please add them to the project. We can sort them out into sub-projects as the need arises.
