JavaScript will only let you enter your name in this form if you indicate you agree to the terms by first clicking the I Agree radio button. If you agree, you can enter your name. But, if you disagree, you will not be able to enter or edit your name. When you disagree, the box is 'locked.' Useful if you require your visitors to accept a disclaimer before downloading software or visiting a section of your members-only site.
