phpBB "Request Filled" type script

Hi,

I am looking for a script where I people who create a thread asking for something, there can be a button or similar where once the question has been answered, the thread is closed with a "Filled" or "Answered" or similar text next to it.

Does anyone know a script which can do something similar to this?

Thanks.

 

have a look on phpbbhacks.com or phpbb.com. Im sure someone has made a mod for it
