I can hardly believe over 4 years have passed since this topic was last discussed. It seems like only yesterday.
To answer your question, as far as I'm aware there isn't a supporters club, and there hasn't been one for some while.
At one time the supporters club was responsible for a lot of activities, such as the match-day raffle, fanzine, and fans coaches to away games. Money raised through membership fees and the occasional quiz in the old bar, were used to purchase Chippy's costume, the large England flag, new skins for the drum etc. The football club elected to bring match-day operations under its direct control using its band of wonderful volunteers.
I still believe supporters clubs have a valuable part to play. Unfortunately, when I've discussed the possibility of forming one, a common view expressed is that to do so, would be in some way be subversive and an act of disloyalty to Neil.
