I'm trying to find where to go in Drupal to find out how a user register form is displayed.
If the url is user/register, a person is routed to a standard registration form.
However, if the url is user/register?destination=voucher, then that person is routed to a user registration form that mimics our popup modal registration form, however, is not in a popup. This is not the regular registration form.
I want to find where this is set so that if a destination parameter is in the url, to go to the standard registration form.
