All,
(Isn't the internet great. Now instead of putting my foot in my mouth
with only a few close people to see me do it; one can perform this act
with an audience of hundreds! If this were a public list, then some
misguided fool would also archive it to CD rom for posterity)
Chip or Storey,
How many people are on your list now?
