I have a problem on how to log in to yahoo messenger

Hi , when you enter your username and password in yahoo messenger , you are logged in. To log out of the yahoo messenger, click on messenger, which is in left top side of yahoo messenger . when the drop down open's, click on sign out. Now you are logged out of the yahoo messenger.

1. Click on the Yahoo! Messenger icon found on your computer desktop, or enter the program from the Yahoo! home page. Log in to Yahoo! Messenger with your user ID and current password. Click the "Yahoo! Messenger" link when the Yahoo! Messenger window opens.
   
2. Go to "My Account Info." This will take you to the Yahoo! Messenger account information page.
   
3. Find the link that reads "Change Password." Type your old password into the first field, then type a different password into the new password field.
   
4. Enter your new Yahoo! Messenger password into the next form field to confirm it. Save the new password into your Yahoo! Messenger account.
   
5. Log out of Yahoo! Messenger, then log in again. Test your account by entering your user ID and new password.
   

Logging into Yahoo messenger is similar in a way to logging into an email account, a log in ID and a password are required.
