Yes, please do get rid of the old one. If you are uploading a new member tree or if you are uploading a new Rootsweb tree and/or World Ancestry Tree, get rid of the old one. I see so many Rootsweb and/are old World Ancestry Trees that are mostly duplicates of old ones-just uploaded at a different date, sometimes days apart with just a little new data added. It certainly makes for lots of clutter. Actually, and someone correct me if I am wrong, to my knowledge it is impossibly to add a World Ancestry Tree through Ancestry.com. I believe teis can still be done through Rootsweb but not through Ancestry as was formerly done.
