GEDMatch is a service started by an ad-hoc group and sister surname study to ours: RogersDNA. Initially provided to store and compare family trees, it was expanded to dsupportAutosomal test matching. It is the only service to support most of the autosomal test result files and make comparisons between them. Thus allowing any relative from any test company to find other relatives. It does require you explicitely upload your result file there.
