Reminders are your own notes on the calendar: "Remind me Monday: Priya back from leave, finish the review".
Add a reminder
From a unit: on the unit screen, choose Remind me…, pick when (Tomorrow, Monday, In a week, or a date) and add a short note. It links back to the unit.
From the Calendar: choose New reminder.
Your reminders
They show on Home and the Calendar, and under My reminders on the Calendar page, where you tick them off when done.
Reminders are private: nobody else sees them.
Reminders appear in Conform; they aren't emailed yet.
