The Off-Trail Magazine Publisher's Association, formed 19 June 1954 to provide British fen wit an equivalent of FAPA. Ken Bulmer and VinĀ¢ Clarke organized it, and were first president and first Association Editor (respectively) of the group. "We weren't proud", says VinĀ¢; "we borrowed wholesale from the rules of FAPA." This isn't quite right, since FAPA's Secretary and Vice-President duties were combined with, respectively, the Association Editor's and President's, and the group was smaller (45 members plus the Keeper of the Printed Books British Copyright repository, carried as "Member #0"]). Founder members included eminent Anglofen like Chuck Harris (first Treasurer), Joan Carr, Ron Bennett, and Archie Mercer. The group grew rapidly; original membership of 25 had to be increased to 29 with the first mailing and later to its present level. Beginning in 1956 it became extensively infiltrated with Americans and some alarm and despondency over possible loss of British character was heard.
