Never mind, after more digging I’ve discovered I seem to be able to do what I need using the following filters:
- bbp_user_can_view_forum
- bbp_current_user_can_access_create_topic_form
- bbp_current_user_can_access_create_reply_form
I found these in includes/users/template.php.
Thought I’d just leave this information here in case other people want to do the same thing
