  2. I see you answered your own question and that's ok with me; however, it is not ethical to type in my name as the author of that answer. I didn't answer that question. My computer shows you used the same computer to type the question and answer. Shame on you for trying to palm that answer off as mine. That could get you banned from this site and quickly. If it happens again I shall do so.
