        if (wp_verify_nonce($_POST['nonce'], 'wpcfur_register')) {
            global $wpdb;

            $full_name = trim($_POST['full_name']);

            $split_full_name = explode(' ', $_POST['full_name']);
            $first_name = trim($split_full_name[0]);
            $last_name = trim($split_full_name[1]);

            $email_address = trim($_POST['email_address']);

            $default_password = trim(get_option('wpcfur_default_password'));

            $check_email = count($wpdb->get_row("SELECT ID FROM {$wpdb->prefix}users WHERE user_email = '$email_address'"));

            if ($check_email) {
                $response = 'email_exists';
            } else {
                $userdata = array(
                    'user_login' => $email_address,
                    'user_email' => $email_address,

                    'last_name' => $last_name,
                    'display_name' => $full_name
                );

                $user_id = wp_insert_user($userdata);

                $headers[] = 'Content-Type: text/html; charset=UTF-8';

                $subject = trim(get_option('wpcfur_email_subject'));
                $template = trim(get_option('wpcfur_email_template'));

                $template_placeholders = array(
                    '[name]', 
                    '[password]',
                    '[email]'
                );

                $template_replacements = array(
                    $full_name,
                    $default_password,
                    $email_address
                );

                $message = str_replace($template_placeholders, $template_replacements, $template);

                wp_mail($email_address, stripslashes($subject), stripslashes($message), $headers);

                $response = 'success';
            }

            die($response);
        }
