You will have to use the 1st category you add to ur board, to display all these forums !!
if u wanna change, u will have to get the fid of your new category, and replace it in
$parentlist = "1,".$fid; instead of
1
if u face any trouble, for example they are not appear, manually add 1 forum to that category
