I am looking for a forum for my wordpress website, where users can make a new topic, and can continue viewing their topic, however in that forum, I don't want them to be able to see topics created by other users by default. I only want moderators and administrators to be able to see all topics.

I also want moderators and administrators to be able to hide comments/replies from users so that only moderators/administrators can see them.

Thank you.
