can you help me with facebook?

[bernard99]

It is hard to understand what they mean when I arrange my privacy setting .... Here what I would like :

I don't want my page to be accessible to anybody that type facebook.com and look up my name... right now we can all see it and i dont like that .

I sometime post with my iphone in ''new feeds'' and it only show up on my page and no one can really see it ...

Also , when I write something on a friends wall , no one can see what I've post in new feed and I would like so , sometime I see what others has wrote on other peoples wall in new feed and for me it wont do that ....

It is really not clear to me , I hope I've been clear enough to ask my question , Sorry if you cannot understand properly as english is my second language but even in french , facebook doesn't make sense to me . Thanks if you can solve some of my problems .
