How my understanding of Diplomacy has changed throughout the module

The basic idea of diplomacy that i had prior to the start of the module was that, considering its title it revolved predominantly around diplomats, and secondly that it was a world used to cover inter-state relations through diplomats.
However my understanding of the term has changed considerably in certain ways as i now understand it to encompass not only the actions and purpose of diplomats and inter-state relations, but also many other practices such as ambassadors, embassies and consulates.
Also i have come to understand the many roles in which these institutions act such as IGO's and summits/negotiations and other groups that have an influence and inportance such as NGO's.
In general, my knowledge, which was basic at the start has not changed much, however it can be said that it has deepend, providing me with a greater understanding of what diplomacy is and how it works and shapes the world.
