In my reading I have discovered that Florence conquered Piza in 1406, gaining access to its port, Porto Pisano. I have also read that they bought the port of Leghorn from the Genovese in 1421. Would it be possible to make a change in the next incarnation of the ICG to reflect this information? (The source is "The House of Medici: Its Rise and Fall," by Christopher Hibbert). If the change can't or feel shouldn't be made, would you please tell me how I might edit the files to make the changes myself? You help is greatly appreciated.
