After Blaine gave permission for me to modify his X-DNA charts I put downloads online at ( http://debsdelvings.blogspot.com/2013/10/x-dna-inheritance-charts.html). Sue Griffith has modified the layout and add ahnentafel numbers with downloads available at (http://www.genealogyjunkie.net/downloads.html). So cool that Creative Commons licenses allow others to build on our work without waiting to get permission so we can all benefit.
