$threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost');

$forumdid= 8;

$foruminfo = fetch_foruminfo($forumid);
$threaddm->set_info('forum', $foruminfo);

$threaddm->set('forumid', $foruminfo['forumid']);
$threaddm->set('userid', Admin);
$threaddm->set('title', 'Test of Script');
$threaddm->set('pagetext', 'This was run from backend');
$threaddm->set('allowsmilie', 1);
$threaddm->set('visible', 1);
$threaddm->set('dateline', TIMENOW);
