To allow entry of any data, a valid email address is needed. Entering a User ID is not necessary. However, if you prefer to have a shorter name to login rather than your email address, then enter a user ID. Anything you choose will be accepted, if it has not already been taken. First time user: Enter your email address and a password of your choosing. Remember this password for future use. To create a user ID: Enter your email address, user ID and password. After the user ID is associated to your email address, you may login with your user ID and password.
