i have i little frustration since i started useing ES (8 years ago!),
There is an awesome option in profiles permission called ""Moderate Event Creation", it help us to moderate new events submissions, this way we control what is add on the website, the frustration is that whre a member edit an event it request a moderation again and we need to validate AGAIN. In our case people edits their events 2/3/4 times and meanwhiles we need to approve evry time.
I believe if we approve an event once when its created no need to approve it again in case of edits, its frustrating for admins and users too.
The ideal solution is to change the moderation behavior (when its approved then no moderation again in case of edits), OR add a second option called "Moderate Event Edit where admins choose to continue moderating events in case of edits or disabling it to not validate every time a user edit his event.
i believe thats make sens
