Perhaps, wikitree's concept is exactly the same (as far as i can tell) as Geni's so copying their work could be considered very poor form.
I even saw a comment on a wikitree discussion board which wasn't particularly complimentary of Geni... having said that for all the rubbish on Geni there's plenty of dross on wikitree too.
Do you want to curate the Quackbs? I am guessing they are your direct ancestors.
