I've already expressed my concerns in the other thread regarding voting differences and personal data storage so the fact remains that not everyone in the community will want to become a member of the GA. This means that the Council (or a similar entity) is needed if you don't want to alienate anybody.
Any volunteer would be welcome to council meetings and tasks. How much did you see? And I do not think this is because of attitude of 'they got elected so why should I care?'. But more a general nowadays attitude. How much volunteers do you think we will have on a Tuesday night meeting without those 5 members that got elected?
