Randy Seaver of Genea-Musings mentioned an article that discusses the Pro Gen group of which I am now a part. The piece by Stefani Evans explains exactly what Pro Gen is better than I can, so I am putting it here for you.
Pro Gen groups 1 and 2 are discussed in the article. I am a member of the brand new Pro Gen 3.
