FYI. That's par for the course on this board. I just ignore that kind of stuff. You were helpful and I've never seen this method, and apparently a few others have not either. So thanks for sharing-most people here are pleasant and helpful/grateful.
eta: I lie-I don't always ignore it. Sometimes I get into a war of words and usually wish I'd just ignored it but I have a big mouth and can't always do it. At any rate, don't let it turn you off this board.
