There is a new organisation, the Universal Film & Festival Organisation www.uffo.org which was formed because of the scam film festivals operating all over the world.
They created a 10 Point Film Festival ethical Code of Conduct with the collaboration of filmmakers and festival directors. It is in the interests of all filmmakers to support this and comment on the code of conduct.
So get involved.
Membership of UFFO is free www.uffo.org
