Sometimes an attendee who visits your event page is too busy, or unclear of their schedule, and does not purchase a ticket right away. In this case, the attendee wishes to purchase a ticket at a later time, and can use the "watch list" function to be reminded to purchase tickets before tickets are sold out.

When a user clicks the "Like" icon on the event page, they will automatically receive a notification email either when the event date is getting close, or when the tickets are almost sold out.

The "Like" icon is automatically enabled for all events, and you do not need to enable any settings as organizer.
