Thanks bira for letting me know.
I actually only did the 3rd, 5th, 6th and 7th changes you listed, the others are really minor and not worth it.
Oh, and you have one
." too many here, and also something else:
Code:
$pagenav = getpagenav($totalposts,"showthread.php?s=$session[sessionhash]&threadid=$threadid&perpage=$perpage".iif(isset($postuserid), "&post.userid='$postuserid", "").");
