A non-relative (as far as I can tell) has duplicated a portion of my tree and refused to merge it.
He is Michael Tandatnick - http://www.geni.com/people/Michael-Tandatnick/6000000030768625977
I have messaged him about this but have received answers that make no sense -- see discussion at: http://www.geni.com/threads/6000000036792532906 & http://www.geni.com/threads/6000000036791814567
Is there anything to be done about this?
