I have been looking around for a solution for themed login and registration.
I found http://www.jameskelly.org/wordpress-plugins/custom-login-and-registration-forms-plugin/ but it is too outdated.
Then I found http://stilldesigning.com/2008/05/01/custom-login-page-for-wordpress/ and it seems like what I needed. However, I am unable to understand its instructions
"you can get the patch and sample login.php theme page from the Trac ticket. Just patch wp-login.php in your WordPress folder and drop the login.php file in your theme. "
How do I apply the patch? There are two files at trac, wp-login.php.diff and sample.login.php. I assume the second file is the login.php that I should place in my theme. How about wp-login.php.diff?
