Hi Mary,
Thanks for checking out Community Events! This is not currently possible out of the box, but you can set the default status that events are submitted into to “Draft” or “Pending Review”, which will mean that events are not published to the front end until you choose to publish them. This would give you the chance to review the event and change the category if needed before it appears on any calendar on the front end.
Alternatively, you could do a customization to change the categories that are displayed on the front end form. Customizations are outside the scope of support that we are able to provide here in the forums, but our themer’s guide would be the place to start if you would like to give this a shot!
We do offer full refunds within 30 days of purchase, so if you’d like to take Community Events for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
