true enuf about dunbar's number - I just like the nice easy 150
   (I think the original was really 147 but it gets rounded up -
   been years since I last read up on it). I remember reading
   somewhere (or in several places) about certain important numbers
   when it comes to grouping people. 150 was the limit where you
   really KNOW everybody - that doesn't even mean that 150 is ideal
   but that its the upper... limit but of course it can slide past
   that and would probably still work. I remember something about
   the number 12 - 12 people was the most people in a different
   grouping - man, I have to look this stuff up again. There's have
   to be some fluidity in the numbers, but definitely ranges would
   be necessary. But I have to talk my hexagon idea... "
