On default installation ES, there are ACL rules to moderate events creation (events.moderate) and group creation (groups.moderate). How is it possible to create new rules to moderate photo upload for exemple ? Where are stored the rule files and how is it possible to create new rule files ?
For exemple, I need to moderate "modification event" or "upload new photo", and I just need to set correspondent state to value 2 (pending approval), how can I do please ?
Thank you
