My LINC trainings should appear automatically by around 8am the day after you begin them. DEI-related Sessions @ Michigan activities are also synced regularly. Activities that are sponsored/operated by College Resource Planning and Management will be added as well, but there may be a delay of a few days or weeks as staff may need to update rosters manually.
While this system currently is built to optimize the experience for activities with a roster of attendees - there are not any restrictions that would prevent you from creating an activity and adding yourself to it, though the system was not designed with this purpose in mind. If an activity is missing you can contact the group holding the activity, if they are in the College of Engineering, and ask them to add it. [This answer does not seem to address the question…]Alternatively, you can add your activity yourself by clicking the MY ACTIVITIES button and then adding this activity.
