Limesurvey the open source software application
… refreshingly easy and free
Once it is set up (= copied to a php-server and connected to a mysql database) it provides a graphical backend interface that admins can use to enter questions and edit the design. All major question-types are possible.
The features I like most are:
- multilingual interfaces/Questionnaires
- The export features and most of all to R!
- The large number of users and active contributors
- open and closed questionnaires
- User management
- all can be found here
