Designed and built an eCommerce site with CartThrob and ExpressionEngine. to sell and manage free downloads of their chemical assessment documents. Users are required to create an account to access encryped links to files that are watermarked with purchase information to protect intellectual property from being distributed without permission.
This is a sister site to www.cleanproduction.org and www.bizngo.org. the three sites run off of one ExpressionEngine install. This allowed the organization to save a lot of money on license fees as well as streamline content management between the three sites with some shared content.
