Mail id from Orkut profile

How to find mail id of a person just by knowing his/her orkut profile? (Of course of the profile who is not a friend in orkut!)

Here are the steps:  

By adding as friend :)

1.Add him/her as your friend.
2.Select friends list and seach for him/her,the email address will be listed along with their name

Without adding as friend:

1.Go to the profile of the user.
2.Click on Ignore user tab given on left side
3.Open your GTalk and click on settings link given on the  top
4.Click on blocked users
Now you can see the Email ID which was previously invisible to you. i.e. in short

Orkut profile>Ignore user>GTalk settings>Blocked users>Email ID

Why I went for this? I needed it ;)
