Login Form:


I am customizing the login page of my site. I would like to enable users to open the main page of my blog when they click on the logo. As an example I attach a picture for the WPMU login page. In this case when I click on the WPMU logo the WPMU homepage opens. I would like to do the same for my blog.
Please, could you tell me which template file should I work on?

Thank you.
