We are simulating a river cruise from Lyon to Avignon and Arles, suspending our disbelief that we are really there, not just each wherever we are using some sort of device, computer or mobile phone or whatever. Like reading a book and suspending one's disbelief that a real Mr Collins is actually arriving to try to woo a real Jane Bennet.
That story is fixed.
Yet this event is happening now, and there are rules, such as Fanny suggesting there be no links.
That is fine, as it keeps text contained in the thread rather than in linked articles.
Yet running the sumlation, that is, posting in this thread, led to realising that while avoiding links to text is good, because people can post short summaries in the thread, it did mean that links to videos could not be included if we continued with that rule.
So to modify the rule would need stepping outside of the simulation itself, so I used [arch] to signify that that was a change to the structure of the simulation, not a part of the simulation, such as is describing the dinner that was served yesterday evening.
