    require_once('./includes/functions_newpost.php');
    $forumid = 2;
    $foruminfo = fetch_foruminfo($forumid);
    $post['title'] = "Discuss: ".$newstitle."";
    $strippedtext= strip_bbcode($newstext, FALSE, TRUE);
    if(strlen($strippedtext) > 350)
    {
        $shortenedtext= substr($strippedtext, 0, 347);
        $shortenedtext.= "...";
    }
    else
    {
        $shortenedtext= $strippedtext;
    }
    $newsdate= vbdate($vboptions['dateformat'], $newsdate);
    $articleurl= "".$vboptions['bburl']."/news/newsarticle".$articleid.".html";
    $image= "".$vboptions['bburl']."/images/news/news".$articleid."_medium.".$extension."";
    $post['message'] = construct_phrase($vbphrase['news_post_content'], $image, $newstitle, $newsdate, $user['userid'], $user['username'], $shortenedtext, $articleurl);
    $post['poststarttime'] = $newsdate;
    $post['posthash'] = md5($post['poststarttime'] . $user['userid'] . $user['salt']);
    build_new_post('thread', $foruminfo, array(), 0, $post, $errors);
    $DB_site->query("UPDATE ".TABLE_PREFIX."news SET threadid=".intval($post['threadid']).", postid=".intval($post['postid'])." WHERE news_id=".intval($articleid)."");
