I have no idea what happens anymore. It used to be the case that old threads would just disappear under default settings and that you could change your timeframe settings so you could find old ones. However, I've gone back recently to find some threads that are only a week or so beyond the default view and they're completely gone. Yet some threads that are older than that are still there. I'm not sure what's going on. I think that's why people are starting what appear to be duplicate threads. Sometimes it's easier to just start a new one than wonder if the old one is still there or completely dead.
