Tom, this is well written and devoid of any antagonism towards anyone.
If anybody wants to dispute any point then all relavent data is in
place in your posting and thus
forces all who disagree to stay on subject without the need for
extraneous data when debating their differences. There will ofcourse,
be some that will be more interested in a fight or profanity in the
absence of comunicable knoweledge , but you are well positioned to just
stand by your posting without retaliating in kind.
Well done
Art
