Sometimes i can help in different communities, not all has high activity.
When a post is flagged to moderator or if a new user register to the community but the new post generated by this user get under moderation queue i want have an option that allow me to notify moderators and administrator; maybe not all only allowed profile that enable this in their profile.
This can be useful because if i did not get an email alert i don't connect to some communities so it's important admin or mod are notified when an action is necessary and when user are awaiting an action from a moderator or admin.
