What a super organisation is this one, the British Naturists and their youth program, the Young British Naturists.
Heres a little from their site:
British Naturism is the UK’s internationally recognised organisation for naturism and exists to unite and support naturists, to protect naturist places and provide more, make social nudity more acceptable across the UK and to provide comprehensive information on naturism and naturists around the world.
British Naturism came into being in 1964 when two societies – The British Sunbathing Society and the British Federation of Sun Clubs merged. We are the UK’s only member of the (INF) International Naturist Federation, which exists for similar reasons to us, but acting and operating across the world. BN is one of 30 member federations in Europe, North & South America and Australasia and INF also has correspondents in ten other countries, including some in Africa and Asia.
See this page for a report on the 2008 INF Congress in Brazil
We have approximately 16,000 individual members and around 130 sun clubs and swim groups who support the aims of the organisation through their subscriptions and receive certain other benefits in return.
British Naturism is a volunteer organisation which means that any members (subject only to a minimum period of membership) can stand for election to the Executive Council, the equivalent of our board of directors. We operate with reference to our constitution, which can be modified and updated at our AGM, at which all members may attend and vote.
BN works hard to raise the public profile of naturism, through media work and by lobbying local and national government.http://www.british-naturism.org.uk/default.aspand their fine young naturist program:
