CMS Change forum.php to index.php
 

Currently with CMS/vB 4.0.1 the structure is set up like this:

site.com/forums/content for the CMS
site.com/forums/forums.php for the forums

I want it the way it used to be which is
site.com/forums/index.php for the forums
site.com/ for the CMS

How do I do this?
