Sign in to Google Sites with your Google Account, and click the Create new site button. When selecting a URL for your site, keep the following in mind:
- Your site name (and URL) can't conflict with an existing site name.
- Your site URL can't conflict with an existing Gmail username (unless it's your own).
- Site URLs can only use these characters: A-Z, a-z, 0-9.
Google Apps site names should be unique within their domain only.
