Ok. So I have FB figured out pretty much to a T, except that a friend posted on my wall today and tagged a friend of hers, and it was about a secret that one of my other friends isn't supposed to see yet. I tried changing who sees the post because I know you can choose who does -- certain people, etc. But I don't get any options to change it for this post. Was it because the other person is tagged?? The only thing I could think of was hiding it from my timeline, though I'm not sure how effectively it hides the post. Anyone?
