This Zen Cart mod puts a drop down box on your login page so that when people sign up for an account on your site, they can choose how they found your website. This is good to keep track of where your customers are coming from - especially if you are doing an advertising campaign.
Currently the selections are: Yahoo, Google, MSN, AOL, ZenCart and Other. Installation includes changing these selections to whatever you prefer.
You can see this mod in action on the login page.
I have revised this mod to work with zencart 1.3.7.
