I am in a middle school and recently created an all school course so I could post events etc. I hid everything in the nav bar except home and announcements and allow students to post replies or make comments. I don't want students to post original discussions. Recently, a student has found a way to post a new discussion and I am trying to figure out how that happened. Is there a way to post a discussion from the e-portfolio function? I could not see it and cannot seem to see where or how restrictions for student posts are addressed in the Community.
