I agree with the analogy to mainstream religions ChunkyDunkin... I see the similar changes happening in our church here in MD...active engagement with new members, actively starting up new programs when newcomers identify an "I wish we...(had/did/could)" ...often putting the person wishing for something in charge of the new effort to make it happen and gathering other members together to help turn the wish into reality...

That's how groups grow and prosper!
