I don't know what format would be most functional. I do see that currently it is all over the place in terms of information in three or four different threads making it more difficult to follow. The mud flood, the cathedrals, the world fairs; they are all connected and I have to leave it to mods to take the most practicable action for a solution.For instance, if I understand the issue well, a thread about whether there was a catastrophic discontinuity of history just before the 15th century, or something like that.
Do you mean a new thread with a title encompassing the existing questions and a merging of the present threads?Another option would be to create a new thread with newly defined questions to tackle.
