An "individual thread dateslip" ... The admin would be able to indicate that a specific thread should no longer move to the top when replied to.

I had implemented this on an old version, and it comes in very handy when you don't really want to close a thread, but you want to get people to move on when they're obsessing about a topic, without having them feel censored/silenced.

This should be pretty easy to implement: it would follow the exact same stream as "Close Threads"... the only difference would be that instead of a "C" indicator for the thread, you would put a "Z" indicator or something... and in addpost.pl, you would check for the Z, and if found, skip updating the lastpost date. Oh, and a new menu item in the admin/moderator menu would be necessary of course.
