bo1972 - First of all I would like to thank you for posting such great, informative messages here. There are times when I have to read your posts at least thrice to fully comprehend the dimensions. At first I used to read them only twice, but then one day it dawned on me that I was really only getting 2 dimensional benefits. Now, I make an effort to read them three times, and I’m finally (I hope) getting all the dimensions. Thank you.
