The Nice messages popup module changes how Drupals status, warning and error messages are showing up by giving flexible stylable nice looking fading little jQuery-popups like on Social networks at hand, provided by the small and fast jQuery jGrowl plugin. It can be activated globally or partially for certain pages / users and prevents the typical cluttering caused by error messages getting in the way by moving the grid and layout of a website up and down.
Writing code on your website using GeSHi? Maybe you'd like that code to be compiled automatically for you?
