Thanks for the kind words, Richard.
I have always maintained that one of the main values of the forum is educational. The forum is basically "BIX 101." I learn a lot from it -both from information provided by contributors as well as from the questions asked.
The first thing I did in my classes when I was a professor was ask, "Any questions about the last lecture or any other subject?" I did not always have an answer, particularly in graduate courses, but I learned a lot by researching the question.
