In includes/functions_newpost.php, find:

PHP Code:

    // ### DO EMAIL NOTIFICATION ###
    if ($post['visible'] AND !$prevpostfound AND $type != 'thread' AND !in_coventry($bbuserinfo['userid'], true))
    {
        // Send out subscription emails
        exec_send_notification($threadinfo['threadid'], $bbuserinfo['userid'], $post['postid']);

        $post['emailupdate'] = verify_subscription_choice($post['emailupdate'], $bbuserinfo, 9999);

        if (!$threadinfo['issubscribed'] AND $post['emailupdate'] != 9999)
        { // user is not subscribed to this thread so insert it
            $DB_site->query("INSERT IGNORE INTO " . TABLE_PREFIX . "subscribethread (userid, threadid, emailupdate, folderid)
                    VALUES ($bbuserinfo[userid], $threadinfo[threadid], $post[emailupdate], $post[folderid])");

            if ($post['emailupdate'] == 9999)
            {    // Remove this subscription, user chose 'No Subscription'
                $DB_site->query("DELETE FROM " . TABLE_PREFIX . "subscribethread WHERE threadid = $threadinfo[threadid] AND userid = $bbuserinfo[userid]");

Surround it with this:

PHP Code:

if (!in_array($foruminfo['forumid'], array(X, Y, Z))) {
// All that ++++ here.
} 


In your newreplys and newthread templates, find:

PHP Code:

<if condition="$show['member']">
                <fieldset class="fieldset">
                    <legend>$vbphrase[thread_subscription]</legend> 


Replace with:

PHP Code:

<if condition="$show['member']&& !in_array($foruminfo['forumid'], array(X, Y, Z))">
                <fieldset class="fieldset">
                    <legend>$vbphrase[thread_subscription]</legend> 


Replacing X, Y, Z with the forumids of the forums you want it disabled in, of course.
