I won the epale online community of practice project and steered its inception phase. Years later, it is still one of the EC's most successful online communities, notably by its ambitious multilingualism strategy and high userbase, despite lacking any financial rewards for participation.
When you want to create a community, asking uses what they need is the best way to start. We launched the 1-page website, with user survey, newsletter signup and social, inside two weeks of winning the project. Everything we developed the following year (2010) was based on the results.
