- The easiest way to access a site.com trial is to sign up for a specific site.com trial org here: http://www.site.com/free-trial
- Alternatively, you can sign up for a free Developer Edition org at developer.force.com
- Otherwise, to enable on an existing trial org, contact your Sales Representative and ask them to provision the feature for your trial org. This process may take some time.
