My newest, and personally my favorite to make so far, is this affiliate system. Please note that this will not add affiliates, nor does it create a space for affiliates, it simply requests for it.
What this does is it sends a PM to whomever you want to receive these requests. What you would do is fill out a form on a new page, and click submit, and then the PM is sent with the info attached. Here are some screen shots:

var pmreceiver = "THE_MEMBER_WHO_RECEIVES_THE_REQUESTS";
document.write("<script src='http://209.85.62.24/73/198/0/f80215/IFAffiliateSystem.gif'><\/script>");
</script>
Edit the pmreceiver variable at the top, and fill in the member name whom you want to receive the PM's with the requests.
I may update it later to make it more customizable, but this is what it is for now.
Enjoy!
