I need some clues about her (her friend, her address, telephone #), I really worry and need to find her, Please help me ( I know the dynamic IP but it only show the city where she lives) I find out her internet provider but they dont tell her information due to privacy law. Is there any way to find some one's clues by Yahoo email address only? Can Yahoo help? How to ask them for help. Any expert who can help me to trail an email, please contact me. She does not log in to check mail for the two months. And her profile is not in any public sites, or yahoo public so no way to do with any search site. Thank you very much for all your help and answers.

• Answer:

  If you know the city that she lives in then all that you need to do is find the listing in the phone book or call the operator and ask for all the people with the same name in that city if you have to call each one of them till you have found your girl.
