> Xavi: But can the tracker be configured to allow users to take the survey only once? That is a key feature that I really like about suveys.
You are totally right. Not coded yet (afaik). But it should... (we are using them for production, and there seems to be no much problem, since the user id is logged together with tracker item submission... (no student submits item twice as fake; at the most, to update this/her survey answers, and teacher has to delete the old item insertion...).
It would be needed also for tests (quizzes), since they are not improved (as feature) in tiki 1.10, but trackers are supposed to be used instead... (and miniquiz plugin also, afaik)
