oops sorry I didnt read (2). You need in the same file to find:

'pts' => array('capt'=>_t("_Posts"), 'query'=>"SELECT IF( NOT ISNULL( SUM(`forum_posts`)), SUM(`forum_posts`), 0) AS `Num` FROM `pre_forum` ",'link'=>'orca','adm_query'=> "",'adm_link'=>""),

and edit the 'link'=>'orca' part to whatever you need it to link to.

'link'=>'forumz.php' for example.
