Agora Voting -formerly known as Agora Ciudadana - is an innovative free software project whose aim is to create a social network for the people, allowing secure and scalable votings via Internet with just your web browser.
Agora Voting is a social web site where anyone can create or join in an agora. An agora has a set of members which can vote in the agora's elections either by direct vote or by delegating the vote.
