MyBB Community Forums

I know this is possible as I've seen Labrocca do it for HF, I'm wondering whether it's a private plugin of his or whether it's some settings, I can't seem to find it anywhere in forum settings. I want to make a section for people to report members in more detail than usual, but so only admins and the person creating the thread can see it. Does anyone know how this would be done?

When you're editing the permissions of a forum, there's an option called 'Can only view own threads?', tick this.

Ah, I see, thanks, I didn't realise I had to go through permissions for each group.
