DNA Print test for ancestry-- is it worthwhile?

[carolinayellowdog]

Hey,

After learning of my second confirmed direct ancestor who was classified as mulatto in colonial records, and two other likely possibilities, I decided to go ahead and order this test today:

It's too late for warnings that the whole thing is pseudoscience--the right amount of money to do this showed up unexpectedly, so I splurged. (Go ahead and warn, though, if it was foolish to do this.) Now I'm wondering if any DUer knowledgable about genetics can comment on the validity of this test, and if anyone has actually gone through with it. If so, what did you make of the results?
