Vunibau Serua - Vunibau Organizational structure

Dear Sir, I'm one of the students at the College of Medicine, Nursing and Health Sciences at FNU. I have questions: 1) Can you briefly give the organizational structure of Vunibau? (For example, what is their Tikina, Yavusa, Mataqali and so forth) 2) What are the actual number of people residing in the village? 3) What are some of the development that had already been conducted in the village? Your help is highly appreciated. Vinaka
