Basically what they say is:
"How do I get started?
First, sign up. Next, log in and submit your referring URL(s) for approval. Once you receive your approval, log in to your account and get banners and links. If you need help testing your banners and links, or if you want to use some of our advanced affiliate tools, simply contact us.

How are my sales tracked?
In MerchantZoo, sales are tracked by the referring URL. If a person finds your website, clicks the banner or link on your site that leads to one of our Merchant websites, and follows through to complete the sale, then MerchantZoo credits you with that sale once the sale is approved (filled) by the Merchant.
You can verify that you received a sale in your Affiliate stats when you log into your MerchantZoo Affiliate Account (the logins box is at the top, left of the page). Sales statistics update once the sale has been approved by the Merchant.
What is a referring URL?
The referring URL is the web page from which a visitor came. For example, if you are on hxxp://www.yoursite.com/index.htm and you click on a banner link that takes you to hxxp://www.merchantsalesite.com/cart, then hxxp://www.yoursite.com/index.htm is the referring URL.
The referring URL(s) that you list in your affiliate account are flagged by the MerchantZoo system to track the clicks that are referred from your site to the merchants' sites. This is why it is important to list your referring URLs."
My question is...Do I have to put links/banners to my site, or can I just url forward my site to the other site?
