Hi there!
Thanks for getting in touch! The event creation and management tools offered through The Events Calendar and Events Calendar PRO are available only to site administrators, but you can extend that functionality to your site visitors with the Community Events add-on! Depending on the specifics of your project, you might also consider the Community Manager Bundle, which includes Community Events, Community Tickets, Event Tickets Plus, and Filter Bar, all at a reduced price compared to purchasing each plugin individually. It’s a great value for projects that hinge on community-directed features and contains almost everything you need to get up and running quickly!
I hope that helps to get you started in the right direction! Let me know if you should have any other questions!
