dear airs, my colleague andreas pashalidis is looking for participants in a survey for a firefox plugin. you find the description and related links below. he is also in cc, in case you have any questions or comments. best, s. We recently released FHEO, a privacy-related Firefox extension that converts online messages into images in a way that makes it hard for computers extract messages, while genuine humans can still read it. http://fheo.esat.kuleuven.be In order to evaluate its usability, we set up an online survey; please feel free to participate and to widely disseminate the link. We do need more participants! http://fheo.esat.kuleuven.be/survey Best Regards, Andreas Pashalidis P.S. Completing the survey takes about 10 minutes, and it is important THAT YOU DO NOT GET DISTRACTED WITH OTHER THINGS while completing it. This is because your answers are timed, and we don't want that you appear to be slow...
