Hi Andreas,

Well, I expected a kind of preview (to see exactly what student will see) in the Overview pane but the preview is already present in the "Edit questions" one. So I would say it would be more comfortable but also redundant...
> Is there some other message than description?
No other message.
> Has the student the capability to complete this feedback?
No, no link nor button to start the feedback.

I did, but I have no message either on html page or php_error.log

Great ! To be perfectly clear, I meant the 'idnumber' field, not 'username' nor 'id'...
Thanks a lot !
