We have given ourselves the mission to develop a module, for integration with Drupal, that features flexible decision making mechanisms, delegatable votes, taxonomy/category influenced controls and weighted voting to begin with.

This is an initiave of the collective of activists and developers involved in the Koumbit project, whose goal is to empower community organisations with technological tools to address the challenges that they face.

You probably want to see the Drupal project page and bugtracker, the roadmap and the specifications we have established. You can also get involved!
