I finished the Login-box theme that copy the WordPress 2.5 appearance, as you can see the image above.
Install it is very easy:
First, unpack the downloaded file and move the wp25 folder into login-box folder, which is in the WordPress plugins directory.
Now, open the login-box.php in a text-editor and change the line 11, replacing "wpclassic" to "wp25".
(Should be like
@define("LB_THEME", "wp25"); )
Remember: Login-box only opens when you are not logged in system, so logout before test it.
