OP: Thanks for having the courage and class to keep the discussion on a civil tone. I have read far too immature, reactionary and ascorbic comments in this forum during the past five years.
@audphile1 : "People are people and will behave the way they choose in that particular moment". ... you are right, of course, but that fact seems both assumed and irrelevant. The OP is requesting for more than that from this group, and rightfully so. He requested civility, curtesy and respect in this forum, and I whole-heartedly support him.
It is truly sad how many people are no longer here to share their knowledge, insights and aspirations simply because of the bad manners of folks who know better.
