If you are looking for the Joomla Module that used to be hosted at this page please be advised that this is deprecated or at least no longer actively maintained.  If for some reason you still need to download the module you’ll find the version for 1.5 (there is no more recent version, although this is reported by some users to work with J! 2.5) here: http://diebesteallerzeiten.de/blog/module-15/. You find some info on how to use the 1.5 module here.
