Hi,
I think it would be good to implement some modifications for Moderators . At this moment when Admin/Moderator deletes a photo/blog/file (etc...), no information is send to owner.
I propose to add mail template and additional pop-up window when material is deleted. In this 'pop-up' window Admin/Moderator will add explanation why material has been deleted. And all information will be sent to user.
What do you think?
