Index -> Interface -> Preferences -> Account Info

This page of the Preferences screen lets you determine what other players see when they click on your name in a User List and Get Info on you. You can write a personal message, include details like an instant messenger handle and home page, and decide which elements of your information are viewable to everyone, no one, or just your buddies. You can also select the game for which you'll receive loot cards when opening packs (Everquest or Everquest II).
