The "Wall" feature of your profile page is a place where your confirmed WorthPoint friends can post messages so they can be viewed by anyone looking at your profile.
To post to a Wall:
Click the Post to Wall link to post to a friend's Wall.
A profile owner can choose to respond to or delete messages that have been posted to his Wall. Responses are viewable by anyone looking at your profile.
To respond or delete a message, simply click the Respond or Delete link beneath each individual message.
If a friend posts to your wall, a reference to the post is also shown to your friends wall.
