If people really felt that strongly that their opinions were being ignored by the club there are other ways that you could try and get somone to sit up and take notice.
The only way you could ever get a reaction out of such a big 'business' (and lets face it, it is a business now, it's no longer a 'club') is to hit them financially.
Clearly there are a hell of a lot of members who dont use the BB so you could never get the message across to enough people to make a bit difference............. BUT if you could contact each individual Chairman for each Local Group, you could possibly get something in motion ie: boycot National Day next year, no local group display stand, no advance ticket bookings etc.......... surely this would make enough of a dent in the bank balance for someone to sit up and take notice?
