When setting up a discussion for the class in under options section I check "users must post before seeing replies." I found out this semester a student can actually post a reply, which then automatically gives them access to other posts, then they can delete their original post and re-post without any indication to faculty that this process took place. So essentially they can view others answers, change their post answer with no indication to me as faculty this took place. Does anyone know if there is a way to manage this issue other than using Similarity?
