title: Handling terms and conditions at Azure AD B2C registration
body: <p>I'm implementing Azure AD B2C in my public facing app and with this approach, new user registration is essentially taking place "outside" of my app on Azure.</p>
  
  <p>How can I enforce users agreeing to my terms and conditions? In other words, I'd like there to be a checkbox and it must be mandatory for users to check it to proceed with the registration process. If the user doesn't check the checkbox, registration should not take place.</p>
  
  <p>I understand through UI customization I can change the appearance of the registration page and there can be a highlighted statement that reads:</p>
  
  <blockquote>
    <p>By clicking Register, you're agreeing to our terms and conditions.</p>
  </blockquote>
  
  <p>I think it would be better if there was a mandatory checkbox though. Is this doable with Azure AD B2C?</p>
  
  <p>UPDATE:
  In Step 5, I'm not seeing "Custom Attributes" -- here's the screen shot:

  <p>UPDATE 2:
  Not allowing me to save after uploading <code>json</code> file for override.
