registration page: what php file controls this

I want to remove the buttons from the bottom of the user registration page in directorypress. I figured I would do this by altering the php file which it is in. The page I am referring to is the one you get to after you click “register” on the login page.

What php file do I need to alter in order to alter this page. I thought it was t/l_myaccount.php but that does not seem to be working. thanks!!!!!
