Until a reunion has occurred, the organizer can edit all details, including the location, date, time, and photo.
To edit a reunion you've created, go to your event page and click Edit event directly below the event name. Make any necessary edits and click Save changes at the bottom of the page. On the next page, you'll have the option to Send Reunion Update Alert to your invitees.
Note: Once a reunion's date has passed, its details are frozen and cannot be edited.
