Some questions about integration of forum to website.

Hello,

First off a link to my site: http://www.strawberrypanic.eu & http://www.strawberrypanic.eu/forum

I know a little PHP, and managed to fetch posts to make a simple news section.

My question:

How do I integrate the forum into my site?

I looked a bit at main.tpl but that's really the other way around, and not what I want.

I want something like this: http://lrguild.org/forum/ where the forum is neatly integrated.

Thanks in advance.
