Oh thankyouthankyouthankyouthankyou!!!!

The link you mentioned FINALLY explained both map and a schwarztian transform in a way that my little luddite brain can comprehend!

I so very much wish that you had been logged on, because you deserve so MANY ++'s for that. I had just decided today that before I left my job for the day, I would understand map and the ST!

Again, thank you from the bottom of my heart.
