Yeah, this menu and the drop down next to the search box are both slated for redesign as well but didn't want to hold up the launch any more. Any specific suggestions on them would be greatly appreciated.
Minor comment: the spacing between the top of the page and the top of the search bar is inequal to the spacing from the bottom of the search bar to the top of the content body. 2px top margin to the #search_form seems to balance that out.
Otherwise, looks great. Love what you've done with the place.
