As they said, it's just a way to keep track of ancestry on part our electronically. I keep mine on kintracts as well but when I get time i am just going to manually make one on PowerPoint. If you had access to a program such as crime links or some such you could use that as well.
I'm going away from kintracts because I've had my entire database disappear even after backing it up. I've had this happen 3 times now.
