Today I googled 'FamilyEcho' and found many accessible family trees. Some are 'Read-Only' but some are editable. That means anyone can edit the information in those accessible family trees without authors' permissions.
So, how can I know that my Family Tree is 'Read-only' or editable in case it appears on somebody else's screen? And if it is editable, which way I can do to keep it private, or at least, make it 'Read-Only' for anybody who enters to my family tree without my permission?
Thanks in Advance.
