Separate discussion permission for edit and delete posts
Current option allows users to: "Edit and delete their own posts"
I might want to allow students to "delete" their posts but not to edit them (or edit but not delete). If Canvas is not going to alert me when a post as been edited (see my related idea: "Create new notification for edits to discussion replies"), then I would want to force them to simply reply to their original post with an update (that way I am alerted to the NEW reply and can also see the original for comparison).
So: change the permissions to allow "delete" and "edit" as separate options (can choose one or both or neither)
