How to add affilaite code box?

http://totallytwilight.forumotion.co.uk/portal.htm

I have my affilaite box on my portal. Some sites I have seen have a box just above theirs with their sites affilaite code in it so people can just grab the code to add. How do I do that?

Create a box on top of the current affliate box with your information on it..
