that's why you must make polls PUBLIC, KWo
Else there's no way to know who voted and what.
and EVERYBODY can vote. It gives the council a good idea of what people want. But in the end, ONLY the council member votes count.
It's a bizarre system, I admit : you might think that normal people in fact "vote for nothing". But that's not the case ; because their vote is here to express their opinion. It has not enough power alone to put it into acts : that's what the council vote is for.
