'''LimeSurvey''' (formerly PHPSurveyor) is an open source online survey application. It enables users to develop, publish and collect responses to surveys. Surveys can include branching, custom preferred layout and design (using a web template system), and can provide basic statistical analysis of survey results. Surveys can be public, or can be strictly controlled through the use of "once-only" tokens for each survey participant.
