Okay, Jean, here goes on Sharing:
On Ancestry main page after you log in, the 2nd Tab at the top is Family Trees. Hover over it to get a list of trees you have (mine is extensive, since I track several lines in different trees & my wife also uses my account). Near the bottom of the list should be an item "More..."; click it. It shows a list of all trees you can access (yours & any you have been invited to). Look for your tree of interest and click the "Manage Tree" item under that tree name. On the Tree Settings page, select the Sharing tab, then click the "Invite People" button. Here you can use either an Email address or their Ancestry User Name. Select One (my email is
weocain@att.net; my user name is Wm3Ocain). You also choose the role a person can have with your tree. Guest is view only; Contributor can add material; and Editor has the same rights you do, so be careful w/ that one (can add, change, delete). Hope that gets it.
I've found several areas in a couple of my trees where dates are bogus, especially when you get back into early colonial America or earlier in Europe. I've got a line back to Robert the Bruce, King of Scotland on my Mother's side, but some of the "documented" births along the line seem a bit off, especially when children come along and the parents are barely 10 or 11 years old. Possible, I guess, but... Anyway, would be glad to help any way I can. I started in the late '50s as a fact gatherer, but have tried hard to document where I've found things the last few years. Still not easy to do, and that doesn't mean you don't run into conflicts any more (ever looked at several US census to "confirm" a birth year??). Will be doing a genealogy trip to New England later this year to try to nail down some of my Ocain line, so hopefully I'll break down a brick wall or two.
