I've created a forum using phpBB and a html website using Dreamweaver CS4. I can call my forum from my website with a simple link, but what I would really like to do is to make my forum look an integral part of my website. I would like to retain say the navigation buttons on the left hand side even when I've passed to the forum, which would allow me to return to any of the websites topics. Can someone give me guidance of how I might do this. Thank you Phil.
