Thanks Jeremy, I was able to use the fetch extension for recording the results, the only problems are that from standard netlogo it posts the request twice (?) and from netlogo-web it originated an error message, so that I wrote a script to remove it from html (it is a generic error message complaining that something went wrong with the reception of the message -- after all the fetch module has the goal of retrieving, not posting things).
However, I think that many users would profit from a simple way of getting data from users, both from the standard netlogo desktop application and the web one, and feeding data on a google form is the simplest way. Anyhow, for the moment, with the inconvenients illustrated above I managed to get it working.
