If you want to BUY something on the site, you log in as a customer. This is on this site where you are now, via the Customer: Login link at the top of the page. Here, your user name is your email address, and your password is the one you gave yourself when you registered as a customer.

If you want to SELL something on the site, you log in as a Designer. To do this, click on the Designer: Login link at the top of this site. Your user name is the one you gave yourself when you registered as a designer, and you use the password you gave yourself when you registered as a designer.

If you want to PROMOTE the site, you login as an Affiliate. You can get to the affiliate login page via the Affiliate: Login link at the top of this site. When you registered as an affiliate, you were given (and sent in an email), a numeric user name and a password.
