This feature allows you to "clone" this event, duplicating all information that you input during the creation process, but keeping none of the sales. This is useful for creating repeat or multiple similar events.
To find this clone function go to your manage events page and scroll down to the event you are wanting to clone. You will see a gear box in the top right hand corner of the event box.
Select the bottom button that reads clone and the system will automatically populate a new event page with the same exact information from the event you just duplicated. Make the necessary changes (time, date, location, etc.). Save your event and you're done!!
