P.S. You guys and gals are simply great! Our tenth member from Wales just became a PRO member! Welcome. I was born in England (my Dad was in the U.S. Air Force) and I admit to a soft spot for the British Isles. However, today I'm IRISH, just like the rest of the world, it seems. Happy St. Patrick's Day!
P.P.S. Keep those comments coming! Remember, I answer every question personally.
