Hi. I have updated the "simpleLogin" module today in order to adapt to the recent skeleton application. As the appearance of the demo is not as fancy as before, I have not changed the snapshot of it though.
Extension library: http://www.yiiframework.com/extension/simplelogin/
Code repository: http://code.google.com/p/yii-simplelogin-module/
