Why not allow them to create their own challenge question with some

FWIW, in our case, we wanted to create a system that the users
could use online.  If you allow users to create their own questions,
and you want a self remediation online access, then they need to
answer their question exactly the same.  It doesn't always work that
way, since people forget things like capitalization, etc.


We've been contemplating a system that converts everything to
lower case and strips whitespace.

As for user chosen questions and answers, they MUST be supplemented
with other information ( e.g. org chosen questions, org data, external
e-mail address account password ). Otherwise some percentage will:

1) Choose questions with a limited range of possible answers:
   What color is my favorite sweater?

2) Choose questions whose answers are available on their
   MySpace/Facebook page.
