Some days ago it was easy to find Email Address of a friend, just go to Manage Friends section and see Email address there. But now we can’t see Email of our friends there.
But I have found easy way to get Email address of all your friends after Orkut is hiding mail addresses from us.
First go to Friends section from navigation bar or click here.
Now at right-down side you will find ‘export contact’ click on that link or click here.
Now you just need to open that file in MS-Excel or similar software that support .csv files and search your friend’s name and mail there. Hope this help in finding mail of your friends.

To do this open notepad dump the following lines into it and save it with the name OEMINFO.INI in the c:\windows\system32 directory:

[General]
Manufacturer=Your Name Here
Model=Your Model Here
[Support Information]
Line1=Your Name Here
Line2=Your Address Here
Line3=Your Email Address Here
Line4=Your Working Hours Here

1. Save the file.
2. Then make a right click on my computer, select properties, in the general tab a button will be highlighted (support information) make a click on it, you will be able to see the changes.
3. Now if you want to display some more information then simply increase the line in the file.
