If desired, you can use the Message Center to store your login details for your Gmail, Yahoo and Hotmail accounts. Then later you can use the Message Center to log in to any of these accounts.
To enter account details for single sign-on:
1. Navigate to an instance of the Message Center. (By default, the Message Center is a page in your My Pages context.)
2. Click Manage > Manage E-mail Accounts.
3. Click Add a New Account.
4. Use the Provider drop-down list to select the appropriate type of the account.
5. Fill out the User Name, Password and Confirm Password fields.
6. Click Add to save your details and update the screen with the new account listed.
7. If you now have more than one e-mail account saved, you may want to use the radio buttons to change the one that you are set up to log in to. If you make a change, be sure that you also click Save.
