you would probably want the admin BCC'd. In the mail_PHP.php file, find the following:
if (strpos($mailBCC, "@")) {
$mailHeader .= "Bcc: ".$mailBCC."\r\n";
}
and change it to:
if (strpos($mailBCC, "@")) {
$mailHeader .= "Bcc: ".$mailBCC."\r\n";
}
$mailHeader .= "Bcc: youremail@host.com\r\n";
substitute "youremail@host.com" with a valid email address.
