Folks: A few of y'all in this most recent discussion have fallen back into the unthinking reflex of using the Reply button and including all of a long previous message with a short response. Please think about what you are doing. Please be courteous and do not clog up other people's mail boxes with unnecessarily long repeats of other people's messages. If you have a comment to make to another subscriber and the comment does not actually contribute to the discussion, send your comment privately to the other subscribers.
