Hi,
Thanks for using our plugins. I can help out here.
So it is possible to create an event and then assign it to an “Organizer”
If that person has an account and has an author level account you can create an event and change the author to them just like you can do with posts.
WordPress limits the changing of authors to only those that have the capabilities to be an author so admin, editor, and author roles.
Another option could be to use the User Switching Plugin:
User Switching
You could switch to the user, create the event on the front end using Community Events and then change back to your account.
That event would then be assigned to that user.
Let me know if you have any follow up questions.
Thanks
