Glad to see such a favorable response. I hope the references I sent will help to explain the ideal behind all this. I haven't had a chance to read it all myself but will study it and see what is necessary to get it started. As to the location, I don't believe they would care where you come from. They most likely are interested in as many samples as possible, but in order for it to be worthwhile for them to come to you, they want at least 100 people willing to participate. If you are living elsewhere, try passing this info on to your local genealogical page, and I'm sure they will be willing to go wherever the demand is. Winnie
