This article covers the methods to modify a post in the Conversations tool. Note that you need the required permission to make any changes. Actions taken on Questions/Discussions will also affect Answers/Replies and Comments associated with them. For instance, if you lock a Question, the Answers and Comments linked to it will also be locked. Comments do not offer any of these actions.
