I've noticed that some threads that started out as sort of a FAQ and then turned into debates were split into two threads; a locked one with the FAQ and a few replies, and one for continued discussion/debate. In one case I quickly found the part that was still open, but all the posts there were marked unread, which made me read through pages again. In other cases, I still haven't found the unlocked part. Will there be a way in the future to split a thread, lock half of it, and have people automatically subscribed to the open discussion part if they were subscribed to the original, and for the site to remember "read" posts?
