That’s a great looking website. I love the typography, dropdown menu transitions and that "table of contents" type thing you’ve got fixed on the left hand side. The slideshow you got going on the homepage looks amazing too.
The bookstore seems kind of off to me. The product information could use more spacing from the thumbnail of the photo, and the authors could be closer to the title of the books. Also the styling of the re-captcha in the "connect" page does not fit the overall style of the website. The arrows on the homepage don’t do anything, but I think that’s because you don’t have many events yet.
very nicely put together luminated, I like the natural tones they really match the style of the product. One thing to consider with the underline/color thing, that can be considered an accessibility issue. Anyone who might be colorblind might have troubles distinguishing link from text, however since it is the main nav, I think that they can figure it out .
