Hi all, I love the way MacRumors have integrated vBulletin into their website, it has all the same colours etc and looks perfect with the rest of the site, it's flawless http://www.macrumors.com how easy is this to do and what steps are needed?

If anyone would like to help me with this i can PM you my website URL to see what the basic sight looks like


Many Thanks
