Facebook app

[mbn]

Hi,

I want to ask about the privacy setting with fbapp (facebook app).

if the forum is locked for users only, does it the same in the fbapp ?
and if someone write comment or new thread, how is the privacy setting in users wall ?
is it show for everyone, friends, or only for friend that is already connected to forum ?

also, if someone reply in the fbapp dose it show his name in forum or facebook ?
