Remote-Learner, our Moodle hosting service, has installed the latest upgrade to Moodle on our sandbox site, and I invite you to test the performance of your respective courses to assure they are working as you expect. You can access this sandbox site at https://campus.extension.org/sandbox. Log in using your normal Campus login credentials. If you run into any particular issues, please send comments to email@example.com. If at all possible, please do this test by November 15.
