Please look at
http://en.wikipedia.org/wiki/Wikipedia:Quickpolls
It is a proposed polling system for backing up sysop and developer decisions in cases like 24 hour bans or emergency desysoppings. Not a voting system per se but more a way to confirm that the community is behind a certain action before it is taken. 80% approval is needed for any quickpoll.
There's a poll on the talk page (of course!) on whether we want to use this scheme, and what could be done to improve it.
In light of this, please also reconsider your vote on the 24 hour policy.
Contrary to Martin's spamming policy, I'm also putting a notice on the talk pages of those who voted against that policy (that seems to be the best way to deal with votes where the options have changed).
Regards,
Erik
