I tried to create an account at diveintomath.com but received Error: Email is Already in Use

1. If you receive an error that says "The email address ________ is already in use. Please enter a different one", that means you already have an account with that email address. 

   
    

2. Try logging in using that email address. See: How to Login
    
3. If you don't know the password for that account, see: Forgot Password
