You are invited to participate in an online debate on the future of HIV/AIDS Communication, and particularly the challenges of evaluation in this field. The debate is designed particularly to help inform the agenda and discussions of a forthcoming meeting of the Communication for Development Roundtable, being organised by UNFPA in association with UNESCO and the Rockefeller Foundation and facilitated by the Panos Institute. This debate will be held over a period of five weeks and is hosted by The Communication Initiative.
