Richard Many thanks for updating the ISOGG Wiki. I find the whole Ancestry DNA system very difficult to navigate. I'd previously added my dad's FTDNA results to my Ancestry account. Last week I tried to update my account to add my mtDNA results from FTDNA but could find no way of doing so. However, I set up a second free "Registered Guest" account using my Googlemail address and was then able to input my mtDNA results. The ISOGG Y-DNA comparison chart is now somewhat out of date, and really needs revising. There is another useful comparison chart which provides a list of project management features from the perspective of an administrator: http://www.isogg.org/features.htm Debbie Kennett
