Hi Jeane!
Thanks for reaching out to us! I’m happy to help you with this topic.
The short answer is yes, requiring users to be logged in to submit an event will link their WordPress user to the event. That is the only built-in way to know who is submitting the event.
That said, there might be other approaches to identify the person submitting the event. For example, you could customize the add event form to require additional fields like name and email.
We have a great article that will get you started on customizing our templates > https://theeventscalendar.com/knowledgebase/themers-guide/
I hope that helps! Let me know if you have any follow up questions.
Best,
Victor
