This is why I have a public tree and use Member Connect on Ancestry - when someone starts pulling data from my tree, I get notified, and after all, what are public trees for? Cousin bait, of course! If you're poking around in my tree enough to want to snag stuff from it, I probably want to talk to you.
I sent a message to say hi - hopefully he will respond!
Update 3/12/2015: He replied!!!!! He's just starting and trying to figure out how to deal with Ancestry.
