Hi. I am not sure if its intentional, but people who are not subscribed to any of the mentioned mailing lists cannot complete query.
As can be seen from this mail, there are people who read mail using e.g. markmail, thereby avoiding the need to be subscribed (and instead be able to choose when to read the mail). I would complete the survey as a good committer, but the text "*This question is mandatory. Please check at least one item." *and no option "None" made it impossible (I actually tried to save without having ticked a box). rgds jan i
