To solve the dateline problem I had to update the timestamp manually
I inserted
Code:
$vbulletin->db->query_write("UPDATE " . TABLE_PREFIX . "post SET dateline = " . TIMENOW . " WHERE postid = ".$post[postid]);
$vbulletin->db->query_write("UPDATE " . TABLE_PREFIX . "thread SET lastpost = " . TIMENOW . " WHERE threadid = ".$threadinfo[threadid]);
to renew post
and thread timestamp to have an 'unseen' post.
Now I'm happy with it
