I thought the email bug was fixed by Orkut..but sorry (happy for some) to tell you the bug still exist.
Here is how you can get the e-mail id of a person who has a Orkut profile
- Start with selecting the profile whos e-mail id you want to know
- Send the person a friend request
- Check out friends section and you will find the persons profile will be shown as waiting for approval.
- If you look on the right hand side you will find the head Manage Contact. In that select Export Contact
- Now enter the Captcha.
If you dont have any further need for the person remove his/her profile from your friends list.
