There's no 'automatic' way to do this. All things like domain, E-mail, Users, Etc must be passed through the panel. That being said it is possible to set up your code to authenticate it self with the panel and submit the information there.
You should be able to search the forum and find some information about this, as it has been asked a few times before. Keep in mind that you are of course responsibe for any content your users should post. At the end of the day it's your account on the line.
