I seem to have found one answer to my question. It involves using the plug-in “bbP Private Groups.” However the solution provided by this plug-in is quite complex as it was made primarily for different purposes. But it does let one create a new set of groups, one assigned to each individual member as defined by their forum role (moderator or participant), and one capability setting for a group is to permit those members to publish and edit replies but only to view topics. I would still like to see a more straightforward solution if someone has one. Thanks.
