I have set up several discussions that have due and availability dates. The intent is that students need to engage in the discussion during a certain period of time. After the availability date, they can access the discussion board, but cannot post.
What I realised is that if students have forgotten, not aware or do not know that they cannot post after the availability date (even though they can still access the discussion), they may think they still can type and post. Only when they clicked the Post, they will realise that the post will not be successful. However there is no message saying that they can no longer post. Hence they will not know and probably keep on trying.
Is there a way for have a pop up message or something?
