From the project’s Gitorious page:
Selectricity is voting machinery for the masses. We help groups make better decisions, more easily. We allow voting, usually in form of ranking a list of choices in order of preference, and have the computer help groups make better decisions.
Selectricity is simple to use and convenient. Anyone can create the simplest election in under a minute and voting is even easier. Results can be computed instantaneously.
Selectricity is powerful and secure. It has been used for electing the boards of non-profit organizations and or choosing the officers of student groups. It is simple and fast enough to help a group decide where to go to dinner or when to have a meeting. It’s flexible enough to be integrated into an outside website or used from a mobile phone.
