MyBB Community Forums

is there anyway to set the portal to be index page for my web root folder, not index page for my forum folder!!?
sorry for my bad English let me explain more,
As exmaple, www.xxxx.com/mybb <----< my forum folder.
the question is ther anyway to put the protal to be index page for the main folder ( www.xxxx.com ) ??????

it is very easy to do:
open portal.php
find:

$forumdir = "./";

and change it with your forumdir
mybb/ for example

cool, thnx coder
