I'll state this here and now, any routes or content that I have personally made are free for anyone to change and update in the future , as long as not used for personal gain , unless they were reskins of others work that needs permission specifically from the original creators.
I agree that these declarations need to be formalized somehow. As an example, consider the recently uploaded Timber Ridge route. I cannot say enough about your hard work and generosity in providing this route. I also do not wish to start the endless debate about what belongs in a route and session. However, all the consists are in the route layer (AFAIK). If I ever wanted to upload a session for this route (and I am not pledging to do so), I would have to make a new route with the consists either deleted or in a session layer. If I tried to upload it along with a new session, I suspect that pitchforks and torches would appear from N3V. My point is that your statement of generosity is just a sentence amongst millions in the forum. Who is to say if anyone at N3v has even read it, and even if so, would have any desire or mechanism to archive it in such a way as to be retrievable?
You see, even in your carefully thought out statement, it is not at all clear that any changes can be uploaded.
