I have a website. To track the mail address of my users on Google Analytics I include the following script:

_gaq.push(['_setCustomVar',
     1,                   // Slot #1
     'email',             // Variable name
     '[email protected]', // Variable value
     1                    // Scope = visitor-level, optional
]);

I'm not a frequent user of Google Analytics.

How can I see the individual email address of users in the GA web tool (no premium account)?
