Installed, no issues what so ever.
The only complaint i can make is i want to make a sub usergroup that has access to the shoutbox, but can't post. (IE they are a registered member, but i also add them to the 'Banned From Shoutbox'). When i try this, they still have access because i guess registered users have access. Only when i make it their main usergroup does it work.

Otherwise, great hack. Thank you for sharing.

For those of you who are getting a 'denied by usergroup' error. Make sure your usergroup has access. If you don't see the shoutbox options in your usergroup then make sure when you installed the hack that you did the LAST STEP.
