Google Sites 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.
Create a single place to bring together all the information your team needs to share, including docs, videos, photos, calendars and attachments. The addition of Google Sites to Google Apps opens up major new possibilities for sharing information within a workgroup or publically on the Internet. Calendering and scheduling just got a whole lot easier.
