In April we arranged a gathering of Participatory Budgeting aficionados to talk about the potential of online Participatory Budgeting (ePB). This meeting has helped form a discussion paper on the subject written by the PB Unit.
In addition the PB Unit have out together some guidance for people deciding whether ePB is something that shuld be included in their PB process. You can see that here.
Both documents are well written and offer really useful insights into this yet to be fully scoped out area.
