The account setup pages have several HTML errors exposed by the W3C Markup Validation Service. The worst is on line 169. A reference to the non-existent ID "user_password" causes the next field, email, to forget the email address submitted. This error bumps the attempt counter, thus giving the user only 3 actual attempts to setup an account.
