I'm having hard time scrolling with this new theme. Simon, why don't you give as an option to choose our own theme? They do it on other forums. If I may suggest this one for example: http://demo.phpbb3styles.net/green_vision
If we can still vote I like the Acid themes, although, I'll admit that they don't really seem to fit this type for forum. Also, is the picture at the top your bookshelf? I just think the books look really nice together.
