Easier to tweak the code.  I'd like to have a central place to hook into
training.  I've got some code that does this, but it still needs more work
before I check it in.  If I manage to get it done, I'll include algorithms
for train-on-everything, train-on-nothing, nonedge, and tte.  I'd like to
have it reasonably easy for someone to add a new style, and reasonably easy
for people to switch between them without having to alter their use

I'd imagine that 70% would be safe enough as a spam cutoff.

Hmmm.  I won't ask about the four ham with that clue <wink>.

You mean it's just http://spambayes.org instead of <a
href="http://spambayes.org">my site</a>?  We'd still generate the
appropriate URL tokens for that, I believe.  (And Outlook still considers
the first a link).  Or is this something more complex?
