As you know, we use WordPress for personal webpages on COR@L server. Recently, we installed the plugin - bbPress, such that every COR@L user with a WordPress webpage can create the forums and create/reply to the topics within the forums, from their personal webpage itself. In case if you did not migrate your personal webpage, please migrate it so that you can start using this feature of forums/topics. Following are the instructions for using bbPress features.
