Kathy/Richard..
                  One of the problems with these
  TECHNICAL meetings is location. You probably get a
  group of people together in a conference room with
  facts and figures to discuss the technical issues and
  reach some resolution. The purchasing people and sales
  people, however, discuss these NON-ISSUES over lunch
  at the resturant or on the golf/tennis court. ;->
  Isn't it great when those that know the least, think
  that they are the experts!!! Sorry to vent, but it is
  SOOOO true and frustrating!!!!!!!!!!!!!!!!!!!!!!
  Enough already, have a great day and enjoy the rest
  of the week.
                                Regards,
                                        Bob Vanech
