Whenever I am doing a project, I have a tendency to add all the features I want, than some how force everything to work together. Later I go back to streamline the code ( sometimes even I have problems reading it ).
This often times produces interesting "raw" code.
I present to you, the raw code I produced for a login page ( and it all works ) !
