We deployed a new website! See discussion of the changes at Coralie Mercier's blog post. She notes: On the surface, the new site implements current web best practices and technologies, donned a cleaner and elegant visual design, and provides information in a more user-friendly fashion.
Under the hood, everything changed. From the complete information architecture to the CMS and the tools that make all of our sub-sites work together.
