Choose a banner, fill in all information and the URL where you plan to put your banner (the banner will function anywhere, but it helps us to monitor activity). Make sure your email address is entered correctly; the HTML code you need to add to your page is sent to your email address.
Click on the Sign-Up button. The code you need to add to your page should arrive in your email in a few seconds. Make sure you do not alter the code in any way; changing it could result in someone else receiving credit for your banner!
Add the code to your webpage and upload your new page. Try clicking on the banner or tex link to make sure it works.
