[Ragnarok]

Thanks guys, that was my problem I was looking at Packs instead of Sets. I had also tried clicking on the Set's link, rather than hovering over it, so that displays a blank page which further complicated it.

Yeah. Unfortunately Google Sites doesn't have the ability to make a placeholder menu item - it has to point to a page. I've put some text on both the Packs and Sets pages now that will direct you to the right place, so that should be less confusing. I also added a bit of a key describing where to find what on the Home page.
