P.S: Auto Save will store the content as buffer in your local computer as cookie, nothing is stored in server side.[/QUOTE]

Are you really sure about that? I have Firefox set to "Never Remember History" which is the same settings as Private Browsing. So no cookies are stored with this setting.
So I reckon the auto save does save on your server which is fantastic, because I always use private browsing when searching adult sites. I had to log off, then I got back on later, logged on, and went to create feedback, looked in the bottom left and clicked the restore saved data and it populated the blog with what I never got to save. All I had to do was put the name of the establishment in the field.
