Instead, destroy it and notify me by reply e-mail And I publically object to CARBINITE, INC's attempt to establish copyright claims on what I write by claiming its their property. Yahoo used to do that too. Am I going to revert to a sig establishing my own copyright claims, something I haven't had to do in a decade or more? I don't mind reading a "commercial" touting the product thats paying the net bills. I am a firm believer in the TANSTAAFL principle, but what I write is NOT CARBONITE INC.'s property.
