| If you want to post somthing on your friend's wall, you go to their profile by clicking their name, and under where it says "The Wall" in the box where it says write somthing, you click and write your message, then hit 'Post' and wait a few seconds for it to show up.
You can't put music on your profile in facebook. It doesn't work that way.
I have no idea what you mean by re-forward back messages. |
