Membership proceeds are used, among other things, to fund the publication of the magazine and to sponsor wargames competitions which fall within the society's remit.
Early members included the actor Deryck Guyler (who served as president of the society[4]), the academic George Gush, Tony Bath and Phil Barker, co-creator of the many sets of rules published by WRG including the De Bellis Antiquitatis wargames rules.
The society concentrates on historical wargaming - a decision to exclude fantasy was made around ten years after it was founded.
[13] Other professional historians who have written for Slingshot include Philip Sabin, Matthew Bennett, Guy Halsall, Paddy Griffith, Nigel Tallis and Steve Badsey.
The magazine has also carried material written by notable games designers (for example, Phil Barker, Richard Bodley Scott, Jervis Johnson, Rick Priestley and Neil Thomas).
