I was making sure as you wanted forums, I think your best bet and the best thing to do for clans is to hop on over to e107.org super easy setup, and it is easy to make themes. It has a forum and member signup incorperated.
if you want an example of e107 (not the forums, just the site layout) head over to http://www.supremegrounds.com thats what it looks like. the forums are made out of invision so you dont need to worry about that
its pretty simple, contact your host and ask him for your mysql info if you dont already have it, then just download e107 from http://e107.org now, just do what the nice little read-me tells you to do. if you want, you could just set forged up as an administrator to your site, and he can set it up for you
