I for one will be having a discussion with the prof before my group's demo
because it is totally irresponsible for the course staff to ignore its
students.
At the very least, the fact that the TA(s) who are assigned to respond to
the newsgroup have done about as much work as I do to turn on a light
switch should be reflected in the marking scheme of the demos. We can't
be expected to make an assumption because there has been no response to a
question and then get hammered on our demo because we didn't read the
course staff's mind as to what was expected.
