3 columns, forum in the middle

[iceinspace]

Hi guys.

I'm redesigning my site to be 3 columns, using a CMS which is all good. When you click on the forum link, I want the forum in the middle column. I'd normally use iframes and have the forum show in the iframe which would be placed in the middle column, but apparently iframes don't work well in all browsers.

So I decided to modify the FORUMHOME template to be 3 columns, and I copy the same left/right column code from the site, into the forum template.

Now that works fine for FORUMHOME, but there's a gazillion other templates that each have a new page template with associated header, body, footer etc, and I don't want to introduce this code into *every* template.

Is there some other way to do this?
