You might have already read it elsewhere that it is possible to reveal the real name of any Gmail user by sharing a calendar in Google Calendar with him. Let me explain how this is done. Google Calendar can be loaded in the header area of Gmail after logging in. A click on settings will load the settings where users can change all sorts of information like the date format and time zone.
A click on the Calendars tab loads the calendars that are currently active. A click on the Calendar loads the details of that calendar with information about the calendar timezone and addresses. There is also another tab in that view that lets the user share the calender with other users.
A click on the Share This Calendar tab displays a list of all users who have access to this calendar with the option to add new users by pasting their email address into the form field.
