So I've been busy working on a new design for my site, and here it is!
It's not launched yet, therefore I can only give screenshots of the forum, but I can link you to a copy of my homepage.
Homepage:
www.thecarforum.net/joom
Forum:

(Everything below that is identical to my current design:
www.thecarforum.net/forum).
Essentially, the homepage and content will have a grass theme, the forums will have a clouds theme, and the gallery (when I get around to it) will have an aurora theme.
Comments welcomed
