When I have some issue with Ghost, I search the forum.
Often I come across old discussion on the same problem. And those discussions often include suggestions to look into Ghost tutorials.
Now the problem is that Ghost has restructured its resources/tutorial/help section and thus the older referenced tutorials result in 404 error.
The thing is that a similar (if not the same) tutorial still exists on Ghost platform. Why not 301 redirect them so that we arrive on the new page?
