Hi again Stefano
The email function for reporting is not a very reliable
method and sometimes works and sometimes does not, but if you want
to use it, then you need to define what must appear in the mail and
this is set in the Quizz Manager, where I would suggest that you
include interactions and score in the report. Best method is to
play with the settings until you get the information you need in
the mail, but once again, this is not a very good reporting
method.
