Damn nice graphics! And a good explanation for the advantages of 
the chi-squared "combining and scoring" treatment. OK, so I'm a 
believer! :-)

Indeed! I've now mostly finished my core word-tokenization and 
training logic, and am presently running sweeps across my 
good/spam corpus to complete populating the database. I'll be re-
working the comparator classes presently, to incorporate this 
chi-2 math. Will keep everyone posted as to progress...

Cheers,
Richard
