We sure have spent a lot of time on this topic. I really don't feel the initial post or UD's reply were inappropriate. It was everyone else who went crazy, no thanks to Ender4track. Dave prefaced his remarks with his usual disclaimer and that should have been sufficient. Grubba's post, albeit a terse, wasn't necessarily demeaning; in his own words he was asking what he thought was a valid question. It was fun for a while, but it's getting old. Let's finish it and get on to something new.
