I have been web casting my classes for a few years now and it has always been a struggle maintaining open access. New York University would prefer to have the web casts be behind a password and I would prefer that they be open access. I think I have the upper hand, at least for the moment.
I do know that access to the web casts has been curtailed over the last few days. However, this is more the result of IT system upgrades than a deliberate attempt by NYU to restrict access. The problem should be fixed by next week and access should resume. I am sorry!
