My intention was to number new threads
I’m not sure I understand this question. Each thread gets bumped whenever it has new posts. I mean, I guess there could be a master-thread with links to new games, and with stuff people might want to refer to (what does “commonly used” mean) but I hadn’t been planning on that.
Yes, the person who wins (or whoever wants to pose a question) should start a new thread, and post a link to it in the old thread. (and I guess the master thread, if there is one.)
