Besides assigning a name to an online presence ("Hello, I'm SpiceGirlsFan42"), Yahoo! IDs allow you to tell the world something about yourself. If you maintain a profile page for your Yahoo! ID, you can list your real name, age, city of residence, email address, interests, and much more. At this time, if you are under 13 years-old then you will not be able to create a Yahoo! Profile on Yahoo! UK & Ireland. For more information on User Profiles, entering relevant information, and creating aliases, see the Yahoo! Profiles help centre.
