title: has_secure_password and email verification
body: <p><code>has_secure_password</code> in rails works well for signing up users by checking <code>:password</code> and <code>:password_confirmation</code> then logging a <code>:password_digest</code> field in the database. However, if I want to be able to verify the email address (by sending an email confirmation) how would I be able to do this with rails?</p>
