In my Parish the meeting details are on the printed agenda that is placed into the Parish Council notice boards (we are two villages) at least 4 days before the meeting. Usually on the Friday so that everyone has a chance to look over the weekend, before the Wednesday meeting.
We often have non councillors attend, usually to complain, but that is beside the point. They get their 3 minutes of "Public time" at the start of the meeting, and I will usually ask the meeting's permission to move the relevant agenda item to the front of the queue. It gets discussed in their presence and as by standard procedures (in any meetings) they only get to speak again to answer a direct question from a councillor routed through me as the chairman. Then they all bugger off, and we never have anyone viewing the boring, every month work of the Parish Council.
Biting the hand that feeds IT
