We support LimeSurvey. What is LimeSurvey?
Develop, publish and collect responses to surveys. Display surveys as single questions, group by group or all in one page or use a dataentry system for administration of paper-based versions of the survey. PHP Surveyor can produce 'branching' surveys (set conditions on whether individual questions will display), can vary the look and feel of your survey through a templating system, and can provide basic statistical analysis of your survey results.
