This page is still in development, but there are basic features available now. At present you can view a table of existing seat reservations, export the table as a CSV document, and cancel reservations. Note that canceling a reservation will automatically notify the email on file that their reservation has been canceled.
In the future, this page will allow you to filter by event, and sort the data by various criteria. There are plans to allow detailed editing of each field such as correcting a wrong email address, or entering any missing data.
