Courtesy of Umbraco.com... " Umbraco is a fully-featured open source content management system with the flexibility to run anything from small campaign or brochure sites right through to complex applications for Fortune 500's and some of the largest media sites in the world. With simple and customisable editing and content creation tools, it's easy to manage and maintain your website exactly how you want it. Umbraco doesn't dictate how you should work - that should be up to you, not your content management system. Editors have as little or as much freedom as they need. And if you don't like the changes you've made? Simply rollback to a previous version. "
