'n case anyone's wondering, my one has been done by starting with a basic family tree (the Wyll-Kath-BoB-Emma-Mik-Skye one) and it kind of expanded over time. If you wanna join, you just have to keep in mind that the parents have to agree to adopting (or whatever) you... that's about it, really. Oh, and you can only join once, so there's no "I was the genetic daughter of ___ and was then adopted by ____" because I like to keep my one sort-of non-complicated. =]

But it's not really official or anything, it's just one of the main two family trees of EoFF (the other involving Cid, Unne, Britt, Asorie, BOU and Kishi, I think?).
