Help Creative Commons to define non-commercial

One of the standard attributes in several Creative Commons licences is ‘Non-Commercial Use’, however definition of this is problematic, universities and further education bodies being a case in point.

Creative Commons are looking to answer their critics [see NC Licences Considered Harmful or Does the Noncommercial Creative Commons license make sense? for example], you can help them work towards a robust definition by completing their Non-Commercial study questionnaire [took me about 15 minutes].
