Judy, I too uploaded to Family Tree Maker many many years ago and alot of mine was without documentation. I wasn't smart enough to put the documentation with it at the time. I also made some mistakes on it unintentionally but as you said you can't undo it and I have NEVER uploaded any more of my trees. I also got sick of sharing and then end up seeing my work added to theirs and my knowing 100% that their work was wrong and had not even been researched. I do use the trees for research and then search it myself to see if it is correct. I don't want to be guilty of adding any wrong info. Sometimes some little tidbit that won't mean much of anything at the time proves to be extremely valuable later. So you do have to go on assumptions & theory & hunches occasionally. Marlene
