Free Q&A platform

Piazza is a question-and-answer platform designed to communicate with your students or colleagues fast. I think it looks like a web 2.0 version of WebBoard, (remember that?).

The system makes it easy to enroll participants, you can suggest that you only want illinois.edu accounts if your participants have your same affiliation. The instructor may enable 'anonymous' posts too. It has a unique way of handling participants' responses in the sense that it allows multiple responses or only one student answer, in which case the students edit the existing response and have to add to it. And there is a "followup" feature that can be used when responses or questions are not clear or a new thread needs to be added. Posts can also be tagged so that it is easier to find them, and formatting is very simple. I hope you find interesting uses for this platform. I will be testing it with the team and we will have some comments after our testing.
