This is so well written and illustrated. Have to give you an extra kudo Billie for the way you laid John's essay out with the line divider for emphasis...and the donkey looking dreadful about another hurtful and truthful article in your Welcome reply. :)
Hi, Aqua! Great seeing you so early today. (well, early in the thread anyway! LOL)
Actually, I had to work on those Dim pictures/paragraphs to get it spaced just right - some of the paragraphs being too short for the pics, etc - so after lots of spacing between some of them, the line divider did seem to help.
I found the donkey at google and had to use it!
