Hi Andrea, thanks for getting in touch!
We currently don’t support a way for organizers to receive notifications for the events they submit using the Community form. Right now, the only notifications that can be enabled are for site administrators under Events > Settings > Community> Alerts.
I can see how that would be a handy feature and would encourage you to suggest it on our UserVoice page. We look there for popular ideas when considering new featured to add to future releases.
Sorry I don’t have a concrete solution to give you, but does that help answer your question?
Cheers!
Geoff
