Top of the page http://blenderartists.org/forum/search.php shows a PHP error:
Warning: Declaration of vBForum_Item_SocialGroupMessage::getLoadQuery() should be compatible with that of vB_Model::getLoadQuery() in [B]…/packages/vbforum/item/socialgroupmessage.php on line [B]21

Also, the form seems messed up with the borders cutting through the form inputs (looks like an alignment error).
