[k3rm1]

Hi there! I've just made this skin [Demo verion]


I wanted to use my vbulletin like as a ''part of the design''
But i know integration is very hard, so i found a website that just added their header and their footer on their vbulletin design. I made like a ''demo image''

I know its not perfect, but i hope u see what i mean.

I was wondering if someone could help me out here. I just don't know how to code / edit vbulletin Skins..
The main theme in the 1st picture is coded
