I guess I've just been lucky...nearly every time I've had a question about a product and sent a message to the vendor, I've gotten a polite response within a reasonable amount of time. There is a "d" option, which I have also used...contacting Clint H. if the vendor has been difficult to reach. He has always replied and helped facilitiate thing. Usually the vendor isn't trying to be evasive but is simply away from the computer for various reasons.
