I am planning on adding a new field to the Moodle user profile page and it will be set to be a required field for new registrants. Will this have any affect to users who are currently in the database? I learned the hard way when I first disabled PayPal on a class and lost all the participants who registered using PayPal. Did find a work-a-round.. I just don't want to lose anyone who previously enrolled because they don't have the new item in their profile. Thanks.
