  so with the default application you get with a new project of mvc 3 i have a working register form and a working login form</p>
  
  <p>but... how do i add more fields to the registration form?
  i know how to add them my model and to the page.. but how do i make the membership keep this new data ill get for the user?
  will i have to make the columns in the database by myself? or does membership knows how to create them automaticly somehow?</p>
