Hi,
Thanks for reaching out to us! I’d be happy to help you 🙂
You could customize the Community Events submission page to add some instructions for example, but that would require some coding. First, I would recommend you to read this article in our Knowledge base about how to customize template files.
In your case, the file you might want to edit is the one located at wp-content/plugins/the-events-calendar-community-events/src/views/community/edit-event.php.
You can then override this template in your own theme by creating a file at wp-content/themes/[your-theme]/tribe-events/community/edit-event.php.
For now, there’s no shortcode to create a submission form, however, feel free to add a vote in our UserVoice! Someone already suggested that feature. The more votes a feature idea gets, the more chances it has to become a new feature 😉
I hope this helps,
Cheers,
Jeremy
