As of February 2016, the passive community was estimated to be more than 11,000,000 users around the world. Chamilo Association Since June 2010, the Chamilo Association has been a legally registered non-profit association (VZW) under Belgian law. The association was created to serve the general goal of improving the Chamilo project's organization and to avoid a conflict of interest between the organization controlling the software project decision process and the best interests of the community using the software. Its founding members, also its first board of directors, were originally 7, of which 3 are from the private e-learning sector and 4 were from the public educational sector. The current board of directors is composed of 5 members.
