hmm, i can think of a way:

open newreply.php
find:

PHP Code:

            $DB_site->query("INSERT INTO post (postid,threadid,title,username,userid,dateline,attachmentid,pagetext,allowsmilie,showsignature,ipaddress,iconid,visible) VALUES (NULL,'$threadid','".addslashes(htmlspecialchars($title))."','".addslashes($postusername)."','$bbuserinfo[userid]','".time()."','$attachmentid','".addslashes($message)."','$allowsmilie','$signature','$ipaddress','$iconid','$visible')"); 


and replace it with:

PHP Code:

if ($threadinfo['forumid']!=xx) 
  $DB_site->query("INSERT INTO post (postid,threadid,title,username,userid,dateline,attachmentid,pagetext,allowsmilie,showsignature,ipaddress,iconid,visible) VALUES (NULL,'$threadid','".addslashes(htmlspecialchars($title))."','".addslashes($postusername)."','$bbuserinfo[userid]','".time()."','$attachmentid','".addslashes($message)."','$allowsmilie','$signature','$ipaddress','$iconid','$visible')");
else
            $DB_site->query("INSERT INTO post (postid,threadid,title,username,userid,dateline,attachmentid,pagetext,allowsmilie,showsignature,ipaddress,iconid,visible) VALUES (NULL,'$threadid','".addslashes(htmlspecialchars($title))."','','0','".time()."','$attachmentid','".addslashes($message)."','$allowsmilie','$signature','$ipaddress','$iconid','$visible')"); 


that'll anonymise the poster.
it'll leave the time in it, because this is need for postorder
