Online Course Platform Upgrade scheduled to begin March 1, 2019. This upgrade does not affect the MMTCP course platform. For other courses: you will not lose access to the online courses in your digital library, and your notes and journal entries should carry over without a problem. Since we cannot fully guarantee that there won't be any issues, we invite you to back up your notes/journal entries if you wish.
