Where to find and adjust your email notifications on Myplace
Step-by-step Guide to editing Email Notifications on a Class Page
1) Log in to MyPlace and click on your name in the top right corner. From the dropdown menu that appears, choose 'Preferences'
2) From the next list choose Notification preferences
Another preference from the list above is Forum preferences, which can allow you to reduce the number of email notifications by choosing a 'daily digest' so that all forum posts for a single day are summarised into a single email.
