A maintenance window to upgrade Moodle, our learning management system, has been scheduled for the weekend of January 19th (10:00 A. M.) – 22nd (8:00 A. M.), 2018. In order that we not interrupt Winterim courses and still get Moodle upgraded in time for the Spring semester, you are being advised that the deadline for grade submission for Winterim courses will be strictly enforced. Grades are due by Friday, January 19th, 2018 at 10:00 A.M. Eastern Standard Time. Users will be locked out of Moodle shortly after 10:00 so that the upgrade can be performed and tested in time for classes to commence on Monday, January 22nd at 8:00 A. M. All users should be advised that Moodle will be unavailable for any use during this maintenance window and plan accordingly.
