When you have a connection to the Internet, the 'Propagation' menu provides easy access to some useful propagation resources. To use it, establish your Internet connection in the usual way, then click 'Tools' > 'Propagation'. A new menu box will show a variety of links to various propagation pages; clicking on any one will open a new browser for the information to be displayed. No Map-Pins or other program resources are required.
