This hack adds prevents Staff Members from posting in closed threads. When a thread is closed, administrators and moderators are still able to post in it. This basically prevents that. There is also an option to exclude selective users from this. I made this modification for a client and decided to put it up here for others to use if they need to.
To install simply import the attached product-denied_reply.xml file. Then you're done.
Altering the Error Message:
It is possible to change the error message that is displayed to users when they are denied from replying in a closed thread. This can be done by going to Phrase Manager in the Admin CP and searching for the denied_reply_error phrase. Then add a translation for the language your forum is in and alter the message as required.

I'm always looking to improve my work for the people that enjoy using it. If you have any suggestions on how I can improve this hack then please leave a comment and I'll see what I'm able to do. Don't forget to 'Mark As Installed' if you've got it installed
