[Plugin: Login With Ajax] Register with Ajax

Theme is not using sidebars so widgets are out of the question.

I used the shortcode to display the login form in a modal window:
https://bit.ly/GJoCph – Click the link “Begin Signup”.

Is there anyway to get the register form to show instead, a shortcode for that?
