Each person who has taken a Family Finder test (or 23andMe or AncestryDNA) should upload to www.gedmatch.com. Each person who has taken a mtDNA test should upload to www.mitosearch.org. Each male who has taken a Y-DNA test (STR/haplotype) should upload to www.ysearch.org. Those corresponding IDs should also be entered on the tester's DNA Tests page in WikiTree.
Family Finder testers should also register at www.dnagedcom.com because there will be more features there soon. DNAgedcom should also be able to work better with 23andMe and AncestryDNA in the near future.
