Hmm.  Also prompting for an email address sounds tempting.  (Remember, the 
password will not be changed until the link send to the email address is 
followed.)

So this would prevent a malicious person from causing the system to send 
unwanted emails, but only for users whose email address is not known by the 
malicious person.  I don't think this condition is worth the added complexity.

I am not in favour of this.  Secret questions would add complexity, and I 
suspect most of them are either written down or forgotten.

This is my objection with the original proposal.  We need some barrier to keep 
malicious persons from trivially causing PINs to be changed.

With my proposed change, a malicious person will need to learn the secret link 
that the system emails, before a password is changed.  (Not impossible to 
hack/sniff, but at least it's not trivial.)
