So my cosplay group made my fanime account and used my nickname as my first name by accident (since no one calls me by first name anyways) so will this cause a problem?? If so is there a way to change the name to my real name??

since i missed the deadline on the pre registration am i still able to register for the full weekend? i hear stuff and read something about the early registration but when i go to the registration is says none available. so if there is one when will it be open??
