Just a suggestion...I think most of the longer term posters here have a good feel for the discussion "styles" of most. If one doesn't like the tone or tenor of responses, say so in one reply and then stop further discussion with the poster (at least in that thread)...rather than let it degenerate into what seems to be an exercise in one upmanship happening a bit frequently lately. Testosterone levels alert! The mods do a good job and cant police everything...posters need to do it themselves sometimes. Unsolicited disparaging opinions of other posters not in a discussion should really not be tolerated by the mods.
(more than a/1 suggestion!)
