You can invite co-organizers to grant others access to your event.
If they are already members of EventKingdom they do not need to register of course. If they are not yet members of EventKingdom they will be asked to register.
Each co-organizer has access to the event and can edit designs, settings and recipients. They can add their own recipients and send to their own or other co-organizer's recipients.
The Sender Name and Email subject can be edited per each sending. So, of 1 co-organizer wants to send from "co-organizer 1 name" and a different co-organizer want to send from "co-organizer 2 name" - this is possible.
