In my congregation there seems to be a bit of a buzz about the whole campaign. A large percentage are pioneering, including most elders (as per BOE letter request)
Previous to that I have found most simply going through the motions of attending meetings and going on the service. Its always been the same few who've always pioneered.
All in all the whole 100 year spiel has done three trick but I very much doubt it will last much beyond the middle of September. Half the hall are on some kind of disability so they need to get back to their mostly imagined physical problems which keeps them occupied otherwise.
