Events typically get added when a presentation is created. If we can't find an event in the location and at the date and time you enter, we will ask you for the title of the event in order to create it.
As the person who created an event you will also be able to edit the other details.
Events can also be added outside of the Presentation creation process. Add an event at this link and, as with the account creation process we will check to see if it already exists before creating it.
