Change the actual file for Logins I have a site and I'd like to customize the login page. I'm using a customized version of the Stark Theme and I'd like to know if there is any way to change the actual file behind the login form so it looks a bit more uniform with the rest of the site. So without creating a new file and redirecting.

Any help?
You can try iTweak Login module to customize the login page. This module have so many settings to customize login form page as well as login block.

You can also try FreshLogin module. It will provide a complete different template.It  can customize as you want.
