hi, i don't know if it is good enough, but may be worth looking: http://jcmc.indiana.edu/vol10/issue3/wright.html (Kevin B. Wright, Researching Internet-Based Populations: Advantages and Disadvantages of Online Survey Research, Online Questionnaire Authoring Software Packages, and Web Survey Services) currently i am using calibrum (www.calibrum.com) for my phd and happened to compare it with other tools the university has license to them: websurveyor (www.websurveyor.com) and classaps (www.classapps.com). these three unfortunately are not reviewed in the article and i haven't done it either! :-) there is also an article about online survey which i found quite useful. Burke, LA. and KE. James (2006), Using online surveys for primary research data collection: lessons from the field, International Journal of Innovation and Learning, Volume 3, Number 1/2006, pp.16-30 hope this is of some use. y ---------------------------------- Yanuar Nugroho http://myprofile.cos.com/yanuar-n Research Assistant & PhD Researcher PREST - Institute of Innovation Research The University of Manchester
