I am taking your personal teaching style and "chatty" approach for granted as being "what I like", as well as your incredible ability to grade your material for maximum access by a  seventy-five year old, "non-specialised" brain like mine.
I liked:
- The practical usefulness.
- The shorter "lesson" times for the SQL seminar.
- The variety of applications in the relationship seminar and the search seminar - I myself am mostly interested in "alternative" solutions to my own challenges.
- The unusual solution in your asset management seminar.
Thank you, Richard, for your excellent work.
