There are two types of screen names in Cosmeo:
Parent Account Screen Name—This is the main screen name for your Cosmeo account. It is selected at the time you subscribe to the service. However, you can change it at any time.
Student Screen Names—These are the individual screen names you set up for each child, friend, or other family member that is using your account. You can create up to four student screen names for each Cosmeo account. There are many advantages to giving children their own screen names. These include being able to set a default grade level and being able to monitor each child's individual work and progress.
