Tonight (Wednesday) our Moodle provider, Moodlerooms, will be applying an update from Moodle 2.7 to Moodle 2.8 in webCampus. It will happen sometime between 11 pm and 5 am Pacific time. It should cause minimal or no disruption, but as a precaution you might refrain from doing anything critical in your courses during those hours.
Please let us know if you have any questions. Thanks!
