thanks. just picked up jonathans book a few weeks ago and handt read it yet...
pulled it off the shelf. skimmed it. its in the first chapter with diagrams. i
gave him expert one on one, but he had to read about 70 pages to really get it.
thanks mark.
to the other posters: i did expalin. however, it is perfectly reasonable to
want documentation and people woh have thought out the explanation in a well
thought out article can have better explanations than i do.
