An anarchist for over twenty years, Iain McKay has been involved in many anarchist groups in the UK. He is currently a member of the Black Flag editorial collective, Britain's leading (and longest-lasting) anarchist magazine. In addition, he has produced An Anarchist FAQ, which summarizes and explains anarchist ideas and history and an introduction to and evaluation of Kropotkin's ideas on mutual aid (both published by AK Press). He also writes on a host of issues for Black Flag and Freedom, as well as on websites (primarily Anarchist Writers). He has recently edited and written the introduction to Property is Theft!, the first comprehensive anthology of Pierre-Joseph Proudhon's writings (2011).
