This just in from FamilyTreeDNA (one of the major sponsors of the Gleeson Clan Gathering in August). They have adjusted the matching criteria for their Family Finder test (autosomal DNA). This will give you improved matches, so if you look at your matches list you may find it has been slightly re-organised - some matches will have become closer, some matches more distant, and some may have fallen off the list completely. The upshot of this change is that you will probably have more reliable matches as a result. And that's good news for all genealogists.
This is just one of several new features that FTDNA will be introducing in the near future so keep tuned for more updates in due course.
