Oh, you mean your greeting - the bit of text appearing at the top of your message wall? You can edit your own by entering your message wall and then hitting the blue "Edit Greeting" button at the top right corner of your wall.

Other than that, you can't do much to edit your wall itself, seeing as it serves mostly as just an inbox for messages. The greeting is the only editable section.
