How do I delete my entire Wall?

At this time, you cannot delete all Wall posts with a single click. However, you can control the visibility of posts by others by following these steps:

1. Choose the "Privacy Settings" option in the Account drop-down menu at the top of any Facebook page.
2. Select "Customize settings" in the "Sharing on Facebook" section.
3. Scroll down to the "Wall posts by friends" section. The drop-down menu will allow you to choose who can view the content that is posted to your Wall by your friends. If you want to prevent people from posting to your Wall, uncheck the box next to the "Allow friends to post on my Wall" option.

You can also control which stories appear on your Wall every time you share content. When sharing something, look for the lock icon. Clicking on it will bring up a menu that lets you choose who will be able to see your post.
