Websites, no matter if simple blogs, corporate sites or e-commerce stores, usually have more than one contributor to the end product. There are designers and administrators who create and build the whole site. But there are also editors who only enter new content, but it needs to be approved and published by someone else. Or there are shop managers, who take care of the e-commerce functions, but don’t need to be able to administer the whole backend. And there are readers, who will only see the front-end at all times.
