since the skew can work both ways (should someone like tim include their 
extracurricular activities in the ham training sample :o), wouldn't it 
make sense to create a number of initial databases with *only* spam in 
them and let the user train an appropriate amount of ham as part of the 
install? anecdotal evidence suggests that just about everyone has some 
ham laying around, yet not everyone keeps spam about.

by having a couple of sample dbs (e.g. 10 spam, 50 spam, 100 spam) you 
could offer the value of kick starting a db,  while reducing the 
potential for skew.

just a thought...
