Integration woes

Hey,

I am trying to slap punbb inside a open source template but it doesnt look quite right.

I have been trying to follow the instructions on how to integrate the forum in an already made template. Copy pasting the header and the footer to main.tpl. But the styles just wont get right.

Can someone check it out, maybe I have done something obvious wrong?
