assessment type notes updated

[John Accardi <John.Accardi@Sun.COM>]

Hello All,

  I was hoping that the wiki would auto generate a message announcing 
when pages were updated but evidently they are not for me.
  (Anyone know how to make that happen?)

  Anyway, updates here:

   I've added a launch page to some discussion at the bottom.

   Thanks,
   John
