I am a owner of three sites, which all of them are sub-sites. I am also not the administrator of the "root" site (which contain many sub-sites including the three sites that I am the owner of it).
Today, one of my sites was "vanished" (which I believe that someone had delete it). How do I trace who delete my site? (Do note that I am NOT the Administrator of the SharePoint Server and the Administrator will not entertain any request from sub-sites owner to check on Server logs)
