Send an email when an event is submitted.
Pending events are excluded from the usual event search, make a custom simpler endpoint and use that.  Only non-admins need to trigger emails for review
store contact name when creating the event (web1 does this) and display it on the email, also with better date format
fiddle with email wording
add a count of pending events with notification emails
