Need some opinions

[BlackMass]

I'm looking for some feedback on the layout of my website. I posted something about this earlier, but since then I have added a bit more. Main content now appears in an iFrame, and I put the forum in an iFrame as well. I'm just wondering if this makes it any easier to navigate through the site, with everything being accessible from the index page, and how does the forum look being in an iFrame rather than it's own separate window?

Also, a ? on the forum ..... I have been looking at the different php files for the forum (I use phpBB) and cannot to save my life find the file that allows you to edit the scrollbar. Is anyone familiar enough with phpBB to point me in the right direction?
