How do I create Piazza groups?
Instructors can create groups, suitable for private discussions (questions / answers) among members of project teams or class sections.
Instructors can manage student and instructor accounts in each group. They can also specify whether students can join groups themselves or not.
Instructors, can change the visibility after a post has been made, from a class level to a group level, or vice versa.
Instructors can post to groups they do not belong in.
Students need to be in a group to post to it or read posts in it.
