In the window "adding a contact" tick the option "Personal data". Enter the information: alias, name and surname, city (region, country) of residence, etc.
Filling in the fields on the personal data, click "search". If something is found, will open display "search results" with the data found by the people. Among these can be entered either e-mail or icq-number.
If the person whose e-mail address you want to know, have a profile on a social network "My world", you can try another "secret weapon". Open his profile and hover over his picture in a detailed form (avatar). Then just right click the avatar and select the context menu item "Copy link address". Open a new window in your browser and in the line enter email addresses, insert a link (right-click on the "Insert"button).
