Every registered user on Homeless Nation has a "wall". A wall is a space on a user's profile page where anyone can write a message. The message is a public one - meaning that anyone can read it.
Step 1:
Go to the profile page of the user on who's wall you'd like to write. You can do this by clicking on their name or on their thumbnail image.
Step 2:
Once you're on their profile page, click in the text box under the title: "Wall". You can now write your message.
Step 3:
Once you are satisfied with your message, click on "Post", located underneath the text box.
Your "wallpost" will now appear on the user's profile page.
