You can't delete an event yourself. You need us to help you with that. If you've created an event accidentally or decided you don't want to use it for any reason, reach out to us through the support email address and we can take care of that for you.
If you might want to access information from your event later, you probably want to archive it instead of deleting it. We can help you do that too. When you email us, just let us know that's what you would like to do.
