According to Wikipedia
"An ambassador is the highest ranking diplomat who represents a nation and is usually accredited to a foreign sovereign or government, or to an international organization.
Sometimes countries also appoint highly respected individuals as Ambassador at Large who are assigned specific responsibilities, and they work to advise and assist their governments in a given area. The word is also often used more liberally for persons who are known, without national appointment, to represent certain professions, activities and fields of endeavor."
So please call me Ambassador Louw - representative to the Internet.
Just a fun thought on a Sunday afternoon.
