Video: Introducing the New

The redesigned is the product of extensive user research, ranging from surveys to sorting exercises, to interactive usability tests, to site metrics and best practices.

Beyond simply updating the design, we have significantly altered the site architecture and terminology and rolled out new features.

Our goal is to deliver a site that allows the majority of our audience to perform popular tasks quickly and easily, while also creating a welcoming user experience that encourages exploration and discovery.

The best way to investigate the upgrades and changes is to browse the site, but below you can find some brief videos highlighting some of the site's new features.

With changes of this magnitude comes unavoidable growing pains, as bookmarks and links to are updated, performance issues are identified and addressed, and users who had grown familiar with the old site adjust to the new layout. We regret these inconveniences and thank you for your patience.

The site you see today isn't an end point but a new beginning. We will continue working to improve the site to ensure quality of content and ease of access.

Please help us by updating your bookmarks and incoming links and by reporting any errors. Additionally, we appreciate your feedback.
