AJAX Login Widget

Hi iv been using AJAX Login Widget++ and its great!
Allows you to register/login from the same page without useing WordPress Interface.

Can somebody more experiensed within this plugin tell me how do i costumize the new-registration mail that is being sent to new users? with the password in it.

(id like to remove the link to wp-login.php that comes in the end of the mail)

thank you!
