Inactive threads and archiving

Howdy folks, so I’m pretty new here and I’m trying to explore the site and get a feel for what’s going on. One unfortunate thing I’ve noticed is, there are quite a few threads that sound interesting but are stale or inactive.

I’d like to ask if we could implement a way to archive these posts? Doing so would make it easier for newbs to find content that is useful for us.

Thanks for reading,
