An advanced survey system for The Civic Platform party

We've created an advanced survey system for the Polish political party called The Civic Platform. Questions and answers in the questionnaire can be text (open-ended questions, semi-open, closed), pictures or even videos (YouTube and Vimeo support). There is a possibility of selecting the following questions based on the answers to the previous questions. The system allows you to manage metrics of the respondents, export results (CSV, XLS formats) or geolocate completed questionnaires. An important advantage of the system is the ability to embed polls on various sites, including Facebook.
