        Subject: KNB Password Reset

        Somebody (hopefully you) requested that your KNB password be reset.  

        This is generally done when somebody forgets their password.  Your 

        password can be changed by visiting the following URL:

        $cgiUrl?stage=changepass&cfg=$cfg

            Username: $username

        Organization: $org

        New Password: $newPass

        Thanks,

            The KNB Development Team
