We had one back in the 2000's where we would move epic threads to a certain board in order to preserve them, and it was stored as part of the old SR archives site where entire site was backed up to from 2000-2006. We kept a link to that archive for years until that database was destroyed during a hosting move. Too bad! There was a lot of great memories that went away when that happened. I am still upset with that hosting service over that.
I don't remember what we called that specific board, but it's certainly possible to create a board like that.
