Thanks for responding, Karen. Good to hear that more than two or three of us are interested in such an arcane subject.
No, I have not contacted Dr. Bercaw yet. My wife and I are right in the middle of a move which along with other things is absorbing all our free time and will cause my PC to go dark shortly, not to reawaken for another two weeks or so.
I have that inquiry in my "To do" file and plan to take care of it just as soon as the dust settles unless I get to it sooner.
Knowing you are watching may cause it to happen earlier.
