68596 phpBB check box additions

I need someone to add a couple of check boxes to the registration process of phpBB which I have installed. These check boxes will be used to get permission to contact the registrant by email later. Box 1: We can contact you by email with organization related information. Box 2: We can contact you by email with information from third parties associated with the organization. Along with this we'll need a way to view the usernames and email addresses associated with people who checked the boxes.
