How Do I Retrieve Messages From Yahoo Messenger?

Retrieving E-mail Messages:
When you sign in to your Yahoo Messenger, Click on the Mail Icon which is just under "Share the Status Message" box on the right side. Once you click on it you will be asked that whether you want to be directed to your Inbox everytime you click that button. If you Click Yes, you will be directly lead to your Inbox but If you click No, you will be asked your Password to go for Inbox again.
