The sub Forum title, "Architecture" to my mind, may deter some posts to this thread. I feel that the forum should invite posts from a wider background. These already include images of bridges and the like, which Joe Blow does not associate with Architects. This has nothing to do with the fact that I am an Engineer who often frowns on Architects. I do feel however that a title such as " Man Made" or " Human Construction" would be more appropriate, excluding such structures as tropical termite nests.
I rest my case.
