Yes, that is possible. Of course, if the main thread refers to things happening in the couple threads, that should be cleared with your respective partner or any player concerned - nobody likes to be godmodded.
If everyone is fine with that, I would like to close the main thread as it is for now, and open a new one - a "Chapter 2", so to speak. For the sake of clarity and keeping track.
What we've had so far could be labeled "Ch. 1 - The beginning", and the next could be "Ch. 2 - The set-up", or something like that.
