I had the FTDNA 37 marker done and it came back as Rib1b2 predicted. Then whenever I logged into FTDNA, it offered me an upgrade to confirm the prediction. I finally did the upgrade, which turned out to be SNP tests for L21+ and M222+.
Now whenever I log into FTDNA, I am told that no upgrades are available. It seems to me that they are saying that the SNP tests are enough, or why wouldn't they offer me a 67 marker upgrade to make more money.
