You can modify this and many other things by going into your profile settings: Click on "settings" in the upper right portion of the screen (beside your log-in name), which will take you to your control panel...click again on "modify profile", which will take you into your profile settings...look for the dropdown menu that states "country", and make your changes, and don't forget to click "save" when you're done.
