I like the layout as it is. Maybe the diagrams could work better, but seems some fixings are beeing made. I do not like SSC layout. This is much better. The search should be as default all ticked, my oppinion. In Bldg requests, maybe a pre-formated online form would be great to just fill-out the camps about data, instead of copying the rich-text form and manual editing. But the rest is pretty good.
I am in Germany for example and participate a lot to the forum. I saw many others, not only americans and canadians participating a lot also. So i do not understand this point.
The site in my oppinion as a database diagram is almost perfect to me. Of course some little improvements like the 100m high line a little bit darker than the others could be implemented... but comparing to other building sites, this is the best.
