Forums / Cotonti / Support / Forum Width

Hello once again! :)

I was just wondering if it was possible to change the width of my forums using any .tpl file and what should I be looking for to do it?

If you visit my site http://www.crazygaming.co.tv and click on the forums tab you will see that there is panels going down the left hand side.  I would prefer to have full width forums and maybe even relocate those left side panels to a different location.  Could anyone offer assistance on how I could do this?  I use the GamePortal theme.

Thanks in advance.
