The United Nations Charter describes the Secretary General – also referred to as the S.G. - as the "chief administrative officer" of the Organization. Equal parts diplomat and advocate, civil servant and CEO, the Secretary-General is a symbol of United Nations ideals and a spokesman for the interests of the world's peoples, as the official site of the UN underlines. The same applies to the position of the Secretary General in a Model United Nations Conference. The S.G. is fully responsible for all the administrative and public relations related tasks, holds the responsibility to monitor all operations and supervises all Board Members and the rest of the staff prior to and during the conference. The Secretary General is considered the Captain on Board, but their work – the overall supervision of the conference – is facilitated by the rest of the members of the Secretariat, namely the Deputy Secretary Generals and the President of the General Assembly.
A delegate in a Model United Nations conference is a participant who represents a country other than their country of origin and deliberate on issues from the country's perspective, and not from the delegate's perspective or point of view. In other words, during the conference a delegate will act as an accredited diplomat of the nation or organisation they are representing and will debate upon the topic of the committee/council they will be placed in, while always respecting the Rules of Procedure.
CHAIRPERSON/CHAIR – PRESIDENT & VICE-PRESIDENT OF THE SECURITY COUNCIL
A Chairperson is a designated staff member responsible for the overall supervision of the Council/Committee they have been appointed to. Prior to the conference, all Chairpersons are responsible for the preparation of the Study Guides, for the correction of the delegates’ Position Papers and for facilitating delegates’ preparation in general. During the conference, Chairpersons chair and supervise all the sessions of their committees and ensure their smooth running. In ARCMUN, each committee has a Main Chair and a Co-Chair, while only the Security Council has a President and a Vice-President. The differences among these positions can be easily understood
The Media Team is responsible of the daily news of ARCMUN. The members of the Media Team will play the role of both journalists and photographers. Duties include taking pictures during the debates and ceremonies, writing reports and updating the social media pages. At the end of the MUN conference the members of the Media Team will publish an online newspaper.
All Staff members play an important role in a MUN conference, since they are responsible for running all the errands during the sessions, such as delivering the diplomatic notes from delegate to delegate or taking care of technical issues. Bearing in mind their contribution to the overall success of the conference, they should be treaten with the ultimate respect, just like all other members of ARCMUN's staff.
