Andrew Johnston is holding a worskhop on writing for international organisations on 25 November 2013 in Geneva:

This workshop is designed to help you transform documents into lively
narratives that engage, inform and convince the non-specialist reader.
It is aimed at communications staff, researchers and others who write for
international organisations.

The workshop covers a wide range of writing situations, from reports and press
releases to web pages and social media. It includes hands-on editing practice.
The group is limited to 15 people to give all participants a chance to share their
needs, questions and experiences.
