The CPC's longest-running fanzine and user group, WACCI was based in Britain and catered mostly for serious users. Its acronym has never been satisfactorily explained.
As well as a (more or less) regular magazine, WACCI also provided a PD library (of mostly CP/M software) and a 'homebrew' library. Some of the CPC's best writers, such as Auntie John, were contributors to early WACCIs. However, the decline in serious use of the CPC inevitably led to a petering out of publication. The last issue was summer 2003, issue 140.
Though WACCI was solely a paper fanzine, a spin-off disczine, EuroWACCI, existed for six issues.
