How do I include the login form with the membership plugin without going to the /wp-admin site

The membership plugin is powering the signup register here .. http://www.happybellystudios.com/tv/register/

How can I get registered users to login from a menu linked called "login" rather than redirecting them to page - http://www.happybellystudios.com/tv/wp-admin

Sorry if this is a dumb question.

Thanks,
