I have an instructor that splits her class into groups and has them discuss among themselves. She wants to know if there is a way that, after the discussion has taken place, she can open the group discussions up where everyone in the class can see each group's board and responses. I initially thought we could accomplish this by unchecking "This is a Group Discussion" in edit mode, but once there are replies you cannot do that.

Does anyone have an idea of how we can accomplish this without too much work on the instructor's part?
