Currently I am not using any genealogy program to track this info but thought it would be so helpful to be able to do so. I am familiar with PAF which allows me to sort and/or search by RIN # or sort alphabetically. But for tracking the DNA participants I need to be able to search or sort by DNA kit #. I don't believe PAF allows sorting or searching by any user assigned number. If it does, I am not aware of it. I am looking for some genealogy program that would allow that. Perhaps a program with more bells and whistles than PAF will allow a search by user assigned number??
