John "Chuck" Connor is a British fanzine editor, active since the late 1970s.
His titles include IDOMO (initially standing for In Defiance of Medical Opinion). It was begun in 1979, and ran through the 1980s. It came joint eighth in Ansible's 1981 "best fanzine" poll; and Self Abused But Still Standing (usually referred to as SABSS), both of which featured a mix of articles, short fiction (predominently science fiction) and poetry.
In the late 1980s, he published a collection of Harry Warner, Jr.'s "All Our Yesterdays" columns on both paper and disk (one of the first electronic fanzines).
