Hi Ana,
Thanks for checking out our plugins! Community Events allows users to create events from the front end of your site, and Community Tickets allows users to add tickets to those events that they create. However, they would not be able to add tickets to events they didn’t create (such as those imported with Event Aggregator) from the front end. Users with admin permissions can add tickets to imported events from the back end, but unfortunately there is not currently a way to add tickets to those events from the front end.
We do offer full refunds within 30 days of purchase, so if you’d like to test out any of our premium plugins, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
