with it, and absolutely zero local modifications, I see the following:Ham distribution for all runs:

My next (current) task is to complete the corpus I've got - it's currently
got ~ 9000 ham, 7800 spam, and about 9200 currently unsorted. I'm tossing 
up using either hammie or spamassassin to do the initial sort  - previously
I've used various forms of 'grep' for keywords and a little gui thing to 
pop a message up and let me say 'spam/ham', but that's just getting too, too
tedious.I can't make it available en masse, but I will look at finding some of
the more 'interesting' uglies. One thing I've seen (consider this 
'anecdotal' for now) is that the 'skip' tokens end up in a _lot_ of the 
f-ps.Anthony
