Autumn concept, Natural Power, Ocean Mist & Pro Profile.
Also the Lightbox plugin has been updated, the new version can be set to automagically generate the correct html for a working lightbox, no more manual html editing needed after adding uploading pictures.

Btw, I’ve stopped adding the main site navigation links (except for pro profile seeing as it’s the one I’m using on the front page) at the top. Yay or nay?
