Andreas - As discussed in http://moodle.org/mod/forum/discuss.php?d=137682#p613593, there is concern about disclosing the user names and times when folks have submitted an anonymous feedback. I can see the concern. The teacher can still review in the logs when students completed but should not be able to determine which response was the first one submitted so that as long as the teacher is not using groups to isolate a particular student then it should be fine. One thing we may want to consider is that if there are fewer than two responses to make it not possible for the teacher to view an anonymous response since it would reveal the identity of the student. In the meantime, I am attaching a simple patch that I believe will address the concerns raised in the forum post. If you are busy, feel free to assign to me and I will check in the patch which I did for 1.9 - I marked this issue as relating to 2.0 but would recommend pushing it back into CONTRIB's 1.9 version as well. Let me know if I can be of help. Peace - Anthony
