Google Sites as part of Google Apps
Google has introduced Google Sites as a part of Google Apps which makes creating a team web site as easy as editing a document. You can quickly gather a variety of information in one place — including videos, calendars, presentations, attachments, and gadgets and easily share it for viewing or editing with a small group, your entire organization, or the world.
Anybody can register and start off. Building sites are very are very simple and you do not need any programing knowledge or even HTML. Advantage of this is the sharing part. Just create a single place to bring together all the information your team needs to share, including docs, videos, photos, calendars and attachments. Invite co-workers, classmates, or your entire organization to edit your site with you to keep it.
