What's the best way to make a user read terms and conditions before continuing a form?
Structure of Form:
Label1 [Textbox]
Label2 [Textbox]
Terms and Conditions [Textarea]
Checkbox ["I agree to the terms and conditions."]
Submit Button
The form has a requirement of checking off the checkbox "I agree to terms and conditions" before submitting the form. The goal is for the user to scroll to the bottom of Terms and Conditions text area before allowing them to check off "I agree to terms and conditions".
One option is to disable the checkbox until the user scrolls to the bottom of the Terms and Conditions textarea... but how what is the best way to tell the user they have to scroll in order to activate the checkbox?
Are there better options?
