You've used Carmen, but you've not used Carmen 10!
Instructors and staff can get "hands on" with the planned update to Carmen before it goes live. You will definitely want to see how your material looks and learn how you can take advantage of new features.
Users will be able to explore the updated system in a "sandbox" environment that includes copies of their own courses. Practice courses will be available to users who don't have courses in the sandbox. Computers will be available, or you can bring your own laptop or tablet.
