Is it possible to hide the chat history from students who aren't participating in a particular chat? I ended up doing a mini-conference with a student in the chat room, since I usually hold online office hours in that space rather than in "conferences." There's no information about the student's grade in our chat, but I'd rather not have other students able to see the particulars of our conversation, which they can apparently do by looking at the chat history. Is there a way to hide that from them?
If, in the future, I decide to use the "conference" feature for office hours instead of the chat, would all students be able to see what happens during a conference, whether they are actually "in" the room/discussion or not?
