Hello guys

I have an HTPC that it acts as a server too, i'm downloading movies, tv shows, music etc on my HTPC and others at home access that shared Drive.

Thing is that I kinda want to setup specific permissions, I don't want them for example be able to accidentally delete something.

How is it possible? When I went to Share->Advanced Sharing->Permissions It will only list my HTPC's local accounts and not others....
