Delegates consistently confuse the United Nations numbering system. It's pretty basic, guys. The first # starts at one and escalates as new working papers enter the floor. For example, the first WP on the floor would be called Working Paper 1.1; the second would be called Working Paper 2.1, and so forth. The second # refers to the amount of times a WP has been edited. For example, Working Paper 1.1 is introduced, but the sponsors later decide to add, change or remove clauses. In true parliamentary procedure, they would then introduce the edited document as Working Paper 1.2.

To be considered a sponsor, a member state must directly contribute to the drafting of a WP. By becoming a sponsor, a member state officially declares that it agrees with the ENTIRE working paper-- all statements, actions, claims and commitments as well as incredibly mundane concepts, like word choice and tone.

For some unknown cosmic reason, most IR 1 students (and some IR 2s) are under the impression that member states must support a WP before they become signatories. This is an incredibly common Model UN misconception. Signatoryship (I may have just pulled a Shakespeare) simply means that a member state would like to see the Working Paper introduced to the floor. Signatories don't necessarily need to endorse any piece of a particular WP. However, signatories must embrace all concepts of a Working Paper once it reaches resolution status (PS: This last sentence is currently being debated. It will be updated shortly).

The word "preambulatory" stems from the word "preamble." "Preamble" is basically just a really fancy word for introduction. Simply put, preambulatory clauses are shorter versions of the first and third part of a position paper (see Writing a Position Paper). They establish background and provide justification for the actions that sponsors later suggest. PCs always begin with verbs, which should be italicized. More often than not, these verbs end in "-ing."

Between the PCs and Operative Clauses lies the name of the appropriate UN body, which is followed by a semi-colon. For example, if the simulation were on the Security Council it would say "The United Nations Security Council;" If it were on UNICEF, it would instead say "The United Nations Children's Emergency Fund;" Got it? 

Operative clauses are simply the requests, recommendations, demands, and actions of the committee. Operative clauses are numbered and begin with a verb in the singular present form. Verbs are underlined. When an operative clause has multiple parts, break it up into bullets using standard number/letter note-taking format. An example is pictured below.
