I have some hopefully constrictive criticism regarding the drupal look and feel. I'm being my web designer nit-picky :)

1. The menu items in the top navigation run together visually. This is a styled list, which is great. Adding some graphical separation like different background colors or horizontal bars would help.
3. The colors and font sizes are not consistent.
   • There are at least four different values of green on most pages. Looks "unprofessional."
   • There are also three values at least of yellow. I would also choose a darker shade of yellow for the headings. The current very light, cream, almost flourescent yellow really pulls on the eye and draws attention away from the content.
