I don't know how possible something like this would be, but I thought I would throw it out there. Sorry if others have already mentioned something like this before!

I'm thinking something like an option to "Archive" a PM that's no longer active and get it off the main PM page, but it's still accessible in an archive section in case you ever want/need to go back to it for whatever reason.

However, I know next to nothing about website building, so have no idea what something like that would involve, and know that there are many other things more pressing and currently in the works.

Thanks!
