Todd..........  That is a very **generous** offer.  I think the problem you
will have is that the design will be somebody's great idea, but not be the
result of a structured needs analysis.  I say that as someone who consulted
in corporate image work in a previous life.  A simple verboten circle with
Van Agony inside would suffice...  if placed centre top of windscreen would
allow oncoming List members to identify another List member with ease.  We
really don't need complicated graphics to do the job, but if you are willing
to put in the work, my hat is off to you!
