Piazza Discussion Forum

We had tried to avoid the proprietary Piazza environment this term, in part because UiO is expected to ban its use in teaching later this year.  But our sense is that the Microsoft GitHub Issues tracker, which we have tried on as a replacement discussion forum for IN5550 this term, does not satisfy all communication needs around the class; notably, several of you have expressed a desire to be able to post questions anonymously.  For these reasons, we have now (re-)activated Piazza as our primary support forum for the class and have sent invitations to all students earlier today (23 of you submitted the second obligatory assignment).
