Meet and Greet Registration Questions

When you register for a meet and greet, do you have to fill out stuff? Or does it just submit your dollyite username and account? My account used to belong to someone else and I dont know what would happen, and I am too scared to click the button (i really dont want to win and not be able to get the meet and greet because my account is under someone else's name). Also, if you change the name on your dollyite profile, does it affect the tickets you bought before you changed it?
