Note that there's another "sendnotification" to find. You need to add this to your hack.

Open "mod/moderate.php"
Find sendnotification($thread['threadid'], $thread['userid'], $key);
Replace with sendnotification($thread['threadid'], $thread['userid'], $key, $message);

Otherwise this will cause problems when your moderators try to moderate any postings.

My board is heavily hacked, so check that this is present in your version of moderate.php.
