Allow user registration on site

Hi,

I want to allow visitors to register on my website, i’ve used register plus plugin for that purpose, and functionally it works well, however, it opens the registration form on the default wordpress interface that is at wp-login.php, however, i want the form to be opened on the website theme that i’ve customized like all the other pages do.

Please suggest me a way to achieve this!

Regards,
Kul.
