The way most password hints work, if a user forgets her password, she gets the hint to help remind her. With MT 3.2, if she forgets her password, it asks her for her hint??? This is not helpful, since if she forgot her password (which she uses often), chances are she also forgot her hint (which she only entered once)!

Typically, users set the hint to be their birthplace. This is to ensure that the system is emailing the password changing information to the correct person.
