Good news..Now your members/users can be an editor or an administrator of Content Management and Calendar Events Module.
If a user is an editor of Content Management or Calendar events they can make edits to the modules and they are sent to pending approval. An administrator will get an email when an edit has been made and approve the change before the change goes live.
If a user is an admin of Content Management or Calendar events they can make edits to the module and the changes go live immediately.
This is just one way to give extra control to users while still monitoring content and not opening up complete access for edits to your site.
