[sudo-discuss] New membership policy on wiki

[Yardena Cohen]

We also need to do something about the old Articles of Association

meeting schedule:

This led to a new person being misled a couple weeks ago:

I could edit this myself but it feels like editing the old AoA should
happen with quorum at a meeting, even though it's technically defunct.
