Facebook wall problem?

[GavinAndStaceyFan]

If it is your friend posting on your wall then he needs to edit the privacy settings. You need to use a laptop or PC to do this.
Get your friend to go onto your wall
Start to write the status on his wall and then next to the blue button that says "post" there should be a little symbol of an earth, or a person, or a gear. This is the privacy setting that the status will be locked onto. The little world means it is public and everyone, regardless of whether they are your friend or not, will be able to see it. 3 small people means that friends of friends of people on the recipients wall will be able to see it. And 1 small person means only the recipients friends will see the post. The gear is custom and you can edit who see it and who can't. Click on the gear and then under the green tick "share this with", on the drop down menu select "specific people or lists". Write down your friends name in the box and select save changes. Only you and him will see the posts
