I would like to thank you for your fantastic job to bring Piazza for us. It is a very useful tool which saved us quite a lot of time answering duplicated questions.
I have used Piazza for the last four quarters at UCLA, and it has vastly streamlined communication between my students, TAs, and me outside of class, especially for large lectures. Students post questions on Piazza, those questions are answered by myself, a TA, or another student, and everyone benefits by immediately having access to that conversation.
I am using piazza this quarter for a compiler class that over time has shrunk to 28 students. I like it!
Instructors can create a Piazza for their class with a single click.
Students and instructors are automatically enrolled with appropriate roles, based on the course roster.
When clicking on Piazza in CCLE, users are automatically signed in to Piazza, so there's no need to remember a separate user name and password.
