Hi Suzanne Not online as such but you might consider using Legacy Family Tree www.LegacyFamilyTree.com ? There is a free version, which is still fantastic. The deluxe version has even more powerful and useful features. One of the features is the ability to share your data with other researchers and allowing them to make additions/corrections for you to review and accept or reject as you feel best. I think it will meet most of the specs you listed. The website has some tutorials which may explain this better. I haven't played with this feature yet but everything else that Legacy has promised has delivered fantastic results!
