Google Sites is an online application that makes creating a class, school, or project web site as easy as editing a document. With Google Sites, people can quickly gather a variety of information in one place -- including videos, calendars, presentations, attachments, and text -- and easily share it for viewing or editing with a small group, their class, the entire school, or sometimes the world. You always control who has access to your site.
Think of building a site in Google Sites as creating a collaborative wiki. A "wiki" is a website that can be easily edited by multiple authors. You can allow others to contribute to the site and add rich media – no html programming required.
