Thank you Gavin for this accurate and supportive comment. The Peoples-uni.org is an example of how to utilise Open Educational Resources, the educational equivalent of the movement for the open publishing of research – of which PloS is such an important leader. The way in which open access to education and to research findings might come together is very exciting, and I am delighted at the interest shown by Gavin for PloS. Peoples-uni.org calls for volunteers to help us realise the goal of providing low cost and credible education for capacity-building in the 'South', through open education. We require those with content expertise in Public Health (for course module development and for contribution to on-line teaching) as well as for those from the scientific and health professional communities who do not necessarily have such expertise, but who are prepared to act as on-line facilitators or in other capacities.
