I don't know about the Globe question so I'll have to leave that to the experienced members. How do I rush a wonder with a great person? Is only a certain type of great person able to do this? I looked for the button icon with the GP in the city that was building the wonder but I didn't see anything about rushing the wonder. Also, is there a limit to the amount of wonders you can build? When choosing what to build, if I hold the mouse icon over a wonder it says something like "national/world wonder: 1 left".
