In addition to the above, cleaning that requires two fields is best
put in the forms overall clean method. This makes it a bit harder
because you can't raise a validation error if you want the error to
appear by the field, you have to insert it into self._errors.
Also, I have an even simpler suggestion. Don't make the user confirm
their email. I'm getting fed up with seeing this on forms all over the
web when it serves no purpose at all. You confirm a password because
you can't read it back. You don't ask them to confirm every other
field do you? </pet peeve>
