Facebook Settings

I went on Google looking for how to make yourself look like you are OffLine on FaceBook but you can be Online on FaceBook at the same Time.

I See how to Hide your Profile this is not what I want.

I want to be able to be on FaceBook and look around and things but not let other People I know See that I am on?

I just See how to take the Profile Down and how to Hide the Whole Profile.

Can anybody help?

 

I believe that is not allowed, and I can understand it, myself.
This might show you a few things, but not crafty spying on others......
