  28. We owe an enormous debt to the GNU project and

    to the Free Software Foundation, as pioneers and leaders of a movement for sharing code freely, so that it cannot be used to coerce and restrict users, and so that it can be improved upon by others. That idea is one of the key inspirations for Wikipedia itself. Erik Moeller, Deputy Director, Wikimedia Foundation
  29. Wikimedia Australia is an independent, not-for-profit organisation, whose primary aim

    is to promote equality of opportunity to access and participate in the collaborative creation of Free Cultural Works, especially educational works, and works about Australia, its culture, natural environment, and Australian news and media. contact @ wikimedia.org.au
