If you area FTDNA customer your results can be automatically updated there by the push on a link on your personal results page. To see some results check out my CROWLEY Dna results page at http://ibssg.org/crowley/ (the results are the lower part of the page) The first chart are those in the project, and the second chart are the matches from Ysearch.
