Fair enough.  My wordlist has been built over a considerable time, so I can't 
remember when I last saw a wrongly classified message.  The only problem now 
is them Unsure ones, as the pattern of spam messages changes.  Inevitable, of 
course, but that's why I wanted to understand the 'further training' 
technique.  It's clearly working, as the numbers decrease each time I need to 
do this.  I save Unsures until I have around 20 in the spam folder, then run 
trainbogo again.

Thanks for the help
