For everyone that has gotten a Family Finder, 23andme, or Ancestry.com test
you can now upload your raw file to www.gedmatch.com

This will allow you to do several things.

1. Find relatives that have taken one of the above tests from one of the
other companies that you have not tested with. Example - You had a Family
Finder test and your 3rd or 4th cousin had a Ancestry.com or 23andme test.
Now instead of one of them having to transfer their results to Family
Finder for a fee you can now compare your raw data at www.gedmatch.com

2. Triangulate in order to find which chromosome and segment you match
other people on. Once you are able to find 2 other people that match on a
certain chromosome and segment then you can try and determine which
ancestor that specific chromosome and segment passed it down to you. Now
everyone else that matches on that specific chromosome and segment almost
certainly is related through that line.

Even if you don't have your results yet you can register at the site at

Hopefully everyone that has test results or has ordered tests from Family
Finder, 23andme, or Ancestry.com is willing to upload their data so we can
use this fairly new genealogical tool.
