1. On Top Black Menu bar select Events-->Add/Edit/Copy/Delete Events
2. The dashboard page for Events will show up and you will see existing events on there.
3. Find the event you want to copy and hover your mouse over the Event Name. You will see a Duplicate option. Go ahead and click that.
4. The Editor window will popup. The Event Name will be followed with (Copy) after it. Change Event Name, Event Description, RSVP Settings, Date/Time, Location, and Organizer as needed. NOTE: It is very important that you make sure to create a date/time that is in the future because if you do not, then nobody will be able to RSVP to it.
5. This is all the basic info you need. I wouldn't change any of the other settings. Very Important!!!! Hit the PUBLISH button all the way in the upper right of your window to actually edit the event. If you don't do that then everything you just entered will not be saved and you will have to start over again.
