I am using the PAF 5 and find it extremely useful. I got it free off of the Familysearch.org under download. I also downloaded a Genviewer (this is what it is called on the website) which will let me open GED files. I got it off of a website called ZDNet.com. It may take a while to download these, I don't remember how long it took me to download. I like the idea of buying the CD but didn't have the patience to wait to get it. Once I get going I don't like to stop, unfortunately, I had sore hands the next day because I set here and typed in 348 names and their info before I realized that I had been sitting here for about 4 hours straight. LOL Hope this helps some. Regina
