not tested, give it a try:

edit newreply.php, find:

PHP Code:

if ($preview) { 


before that add this:

PHP Code:

// Force registered members to rate threads when replying hack
if  ($bbuserinfo['usergroupid'] == 2 AND $foruminfo['allowratings'] == 1 AND $permissions['canthreadrate'] AND (!$rating OR $rating < 0 or $rating > 6))
        {
        eval("standarderror(\"".gettemplate("error_mustrate")."\");");        
        exit;
        }
// Force registered members to rate threads when replying hack 


create a new template named "error_mustrate". This will be displayed when someone sends a reply without a rate..

btw. hack will apply only registered users (usergroupid=2) replies, other usergroups are exempt from this restriction..

enjoy..
