Exclusive? Yes. Restricted? No. This is a public forum after all. I am assuming that there have only been three runs of this material and have been purchased through XMarks. I agree that if anyone had the money to produce their own run of this tartan, that they could. Failing that they would have to wait for an XMarks run and post that they wanted some. In order to post on XMarks one had to sign up, correct? Doesn't this simple fact made it "exclusive" to us?
