Hi Joey,
Thanks for checking out our plugins!
Using Community Events to create events and Community Tickets to sell tickets, users can submit and edit their events via a front end form (you can require them to have an account in order to do so). Depending on the permissions you set for these accounts, they would not be able to edit events submitted by other users (note that events behave similarly to other WordPress posts regarding permissions). So, if you do not give them back end access, they would not be able to see events submitted (by anyone) from the back end.
However, there is not currently an out of the box way to prevent one user from seeing an event by another user on the front end, although it could be accomplished with a customization (see our themer’s guide for more info on customizing our plugins).
Does that answer your question? Please let me know if I can help with anything else!
Thanks,
Jennifer
