When adding students, sometimes you will see the error "an account with this email address already exists."
When you try to add a student using an email address already registered in our system, this error message will appear.
The simplest way to fix this issue is to add the student using their first and last name only (no email address). Then give the student their new student code as it appears in your Student list in the class settings.
Your student can log in to their existing account and enter the new code in their profile (http://game.classcraft.com/profile). This will archive their old character (if they had one) and allow them to create a new one for your class.
