Hello.

I know Xenforo has the capability to make a sub-forum that anyone can post in, but users can only see their own threads (staff can see all the threads) and I know of one forum that uses this to facilitate communication with the staff.

My question is: Is it possible for add additional non-staff users to a thread like that in order to allow them to see it? The use-case I am imagining this for would be a rule violations reporting sub-forum, where we would potentially add the reported user to the thread to allow them to see and respond to a report if needed, but if there is no way to add a non-staff to a thread in such a sub-forum then that wouldn't really work.
