Every Body Corporate Strata in Australia basically goes through something like this at least once a year (by law.) Questions are posed about what to vote on and you either vote for, against, or abstain.

Something like Polis would be good for putting forward ideas throughout the year leading up to the vote, as it would find a consensus of ideas and help shape what you eventually vote on (you decide as a body corporate.)

Some Strata are hundreds of people in size.
