Thread:Feedback/Archiving threads

Is there some obvious functionality for moving one (or, ideally, multiple) threads to an archive page? Or is some other method envisioned for archiving old threads?

If there's going to be automated archiving based on thread "staleness", then there needs to be a way of configuring the threshold on a per-page basis; some pages have orders of magnitude more traffic than others, and thus need much faster archiving.
