The problem is that there is no such thing as a "normal" user when
considering SpamBayes, and particularly the Outlook addin.

Some "normal" users get the vast majority of their ham as html.  I know lots
personally.  Some "normal" users get more plain text - but I don't hang out
with many of them in real life!

I agree 100%.  I fear we are starting to sound condescending - such labels
and telling users "trust us, you really don't want that feature" doesn't
help anyone.

The problem is that we simply don't know.  One man's trash is another's
treasure.  We clearly need more research, but we have to be careful not to
base too many assumptions on testing the mail of us geeks <wink>
