DocJohn, you have so many great quizzes here ... and while I know the main focus is mental health ...
How about something along the lines of a career survey quiz?
Many members here are without work, not just due to the economy, but perhaps due to pursuing work in an area that isn't suited for them, especially with their particular dx's.
Sometimes a member might need assistance changing careers because of a newly arising disorder, or a severe flare of an old one.
A career personality type inventory quiz whatever might assist them in reevaluating - and finding - suitable work.
Just a thought.
