Thanks, I read the codex on the definition of pages and Pages. :S lol.
Maybe it's just me, but i think that if your someone that hasn't used WordPress before it takes some time getting your head around the process of building a site using WordPress. As WordPress is as the name suggests a blogging tool, more complex sites can be hard envision how one might create such a site.
However having said that, once you get your head round it, and realise that you just use different category templates for each type of different page, you begin to realise it's reasoning. Because the beauty of WordPress and other CMS tools is that it generates the content automatically, using includes and other dynamic data processes, it's actually reletively simple to create. (In theory, im still yet to find out)
I just thought i should mention this, because not all designers realise this, it took me a good few hours to suddenly click. I'm always learning how WordPress actually processes everything.
