You are right, Greg. My rant, which was probably uncalled for, is in response to a couple of replies I've recieved from Tom Martin. Most of the folks I've conversed with via this board are more than helpful and have willingly answered my questions, even the less intelligent ones. Tom has, in the past, come across as arrogant with an air that if you're not one of the experts, you are rabble. I apoligize to anyone who may have taken offense. I am here to learn.
