KEY POINTS:
The post of United Nations Secretary-General is not exactly a low-profile job.
But the world's top diplomat, Ban Ki Moon of South Korea, is struggling for name recognition more than a year after taking over from Kofi Annan.
Ban's chief of staff, Vijay Nambiar, sent a memo to staff worldwide dealing with "the question of ensuring clarity and accuracy in the recognition of his name."
The letter said: "Many world leaders ... still use his first name mistakenly as his surname and address him wrongly as Mr Ki-moon or Mr Moon."
