Using Registration Component when Offline

[Davide]

Hello world!
I got one little question. How can I modify to get access to the registration form when site is configurated as offline?

I tried to access to this page http://www.petbooking.it/index.php?option=com_registration&task=register and change/comment following:

Components > com_registration > registration.php

Code:

22 /*{
23 mosRedirect( 'index.php', _NOT_AUTH );
24 }*/

and other but without good result. thank you in advance!
