Installed. I used this hack for the 3.6 series and one of my admins did not know what it was used for because I did not let him know right away, so he set this usergroup as his secondary group....WOW. I never heard the end of it. At first, my webhost and I could not figure out why he could not view the forums until I looked at his info through the admin panel and saw this was checked. My webhost and I were laughing so hard at him, my co-admin that did this to himself, left the MSN chat, furious. ROFL
Needless to say, I did not hear from him for a few days.
