[split] Stolfi's Core-mantle-crust model

[Koen G]

Marco's core-mantle-crust diagram is in the core-mantle-crust thread

So I don't agree thay splitting makes things harder to find. If I didn't split, the Stolfi posts would soon be buried and forgotten in Mark's thread.

Apart from that, the problem you mention is a real one. That comes with the forum format, and I don't quite see how it can be helped. 

I once tried to work with curated threads, where I would collect the results of discussion threads in a locked subforum. You are not allowed to view links. Register or Login to view. 
It hasn't been used since 2018. Still I'm very happy with the way these threads turned out. But I quit doing it since I felt like I was the only one really interested in it (even though people like JKP and Marco and Vviews provided a lot of input in the discussion threads).
