I want to edit the elements and the button on the sign up page but in _form.phtml there is a message I cant understand. // you can customize form output - for example // $renderer->setTemplateForClass('html_quickform2_container_fieldset', '<fieldset{attributes}><qf:label><legend id="{id}-legend"> {label}</legend></qf:label>{content}</fieldset>'); How do I control which form elements to include in the sign up form as well as change the button?
