How can I find a lost friend's email ? I know that probably he has a yahoo email address and lives in the USA

Question

Obviously I know his name and I know that he lives in California .

Answer 1

You can try searching the member directory.
http://members.yahoo.com/
But finding him there would depend on how much info he has on his profile. People rarely give out their full names on profiles & e-mail accounts.
Good luck.
