Wikitree Let's build one human family tree

[dragonfly]

I have just started using wikitree, which is just what it sounds like. A family tree that can be added to by anyone. http://www.wikitree.com/

Well, they have instituted some policies and hoops to jump through, apparently to weed out some troll-like behavior they've had in the past. But it's not too hard to figure out, and it's a free way to be able to link in to other people's trees and knowledge.
