Hi José,
      I realize you proposed some rules in an attempt to resolve disagreements. A priori not a bad idea, if the rules are not rigid. One of the things you wrote is: " I say that we agree up front that the people who choose to participate speak for the whole list.  Anyone who disagrees, say so up front.  No second guessers."
      To me that's unacceptable. Only I can speak for myself. And whether or not others on the listserv answer you is irrelevant, because no mature person can willingly surrender the right to speak for him/herself.
