How often do you log in at your TYPO3 account(s) and how often does your customer look at the really boring login form?
It is time for a change and the extension chloginskin makes it possible! Until now you needed to hack into extensions (t3skin, skin_grey_2,...) to modify the backend login.
Now you just need to install this extension, go to the extension manager, set the path to the css file, delete the cache and finally of course edit the css file and you are done! You can even set different css files for different urls.
The following examples should show you what is kind of possible in very short time! Send me a pic of your new login if you want to - I am interested!
