Larry, you have nothing to apologize for. At the end of the day, if I'm doing it myself, it's up to me to determine whether someone's advice or recommendation is valid. Yours has always been focused, helpful and, most of all, educational. There are several systems I understand a little better having read what you have to say. It pains me that you might have any misgivings about your contributions. Thank you again for all your help.
