Electronic democracy is still far from being realized and several issues must be solved in order to make it possible. The quantitative problem of popular participation is one of them, but it can be mitigated through automation. This Chapter proposes two main applications that may help building a multilevel digital agora where demos, lawmakers, governments, and public administration may cooperate. The first is related to the integration, in each platform used for this purpose, of specific decision support systems. The second is inherent in the use of IT tools that, integrated into a digital agora, allow to transform the multiplicity of individual contributions into a general will.
