During sessions, communication is not limited to the verbal speeches. Representatives may pass notes to each other while in formal debate or moderated caucus. Notes can be used for questions, asking support or coordinating your strategies. During sessions there may be note-passers present to deliver your notes to the addressee or you may simply have them passed along.
Note-passing is strictly for diplomatic purposes only, not for inquiring where to have dinner or other unrelated matters. Note-passers and chairs reserve the right to read notes or suspend note-passing when they deem it necessary.
