I have used Jeff Star's tutorial for creating my own custom login form <http://digwp.com/2010/12/login-register-password-code/>. It works great, but I have one problem. On the reset password form, if someone enters their username incorrectly (so that it doesn't verify), they get kicked to the default wp-login.php?action=lostpassword with the error message.

Is there a way to redirect to my own error page?

Thanks!
