You are able to view your own registrations by going to "My Activity" and clicking "Registrations."
From there, you will see a calendar view of all of your registrations for that month. You can toggle to a list view for your registrations by clicking the list icon at the top right of the calendar.
To view more details about any event you have registered for, click under the far right drop down next to the event name and choose "View Details." You can also use this to update/ cancel your registration, message the organizer, or to add an impact for this event (choosing to add an impact from here will automatically populate the event and group).
