I very much like the models.
Though in terms of this "having too many threads" thing, I'm going to agree with the rest that you should try to stick with one. The edit button isn't there for nothing. If there's an update to the original post, just tell us in the chatbox and we'll look into it.
Honestly, starting a new thread to me sounds more annoying. It'd be like starting up a new website, and every time you make an update you start another one.
