Much to the contray I don't expect them to be distributed normally
but I expect the sampling to suggest a normal distribution i.e.: that
there should be a good rep. of the average keeper (15+ spp) as
compared to the beginer (1+ spp) or advnaced (50+spp). If we are
getting info mainly form the 1+ crowd we can not draw any real
conclusion as to what is out there. Where as if we have a lot of
advvanced people (lets say 10% of the AKA population) it woudl be
hard to say what the average person has (who reps the other 80%
of the AKA).Idealy we want to see that most submissions were
from the 15+ crowd who rep 80% of the AKA. (I'm pulling numbers
out of my head here by the way.)

I hope every one on some one's block has some A. mimbon
blooming in the cool basement.
