Hey there and thanks for reaching out!
It is possible to allow those who submit events to create tickets for their events and for you to take a cut of those sales if you use Community Events with Community Tickets.
Charging for event submissions, however, is something that Community Events does not do right out of the box. I have heard of others using Community Events and Restrict Content Pro together to create a paywall between visitors and posting events, so that might be worth checking out. 🙂
Do you think that will do the trick for you? Let me know!
Cheers,
Geoff
