Great job on the new site. My only (small) comment is that the pink text is fairly hard to read against the white background. You might try a much darker pink, or black or navy.
Also, since I'm on the web review crew for DG, I noticed that you need to add the disclaimer at the bottom of each page. You can find all the info you need here:
