WikiVote

A WikiVote is just a vote taken via a wiki. Some issues:

• can you change a vote after you make it?

Sure. You can remove your vote simply by removing it from your User:UserName/MyVotes page perhaps to switch to support an another more credible, better-argued campaign.

• which w:voting system should you use? for what purposes?

The question is already anwsered elsewhere, though disagreeing views are welcome. The current proposition is a one-to-one vote: You have one WikiVote per issue. A more interesting question is how and by who is defined what is an "issue". Obivious issues are a company, a brand, a product and a product group so we should start with these basics and then expand.

• how is w:user authentication performed? By just accounts and passwords, or by IP number, or what?

The existence of multiple levels of authentication is the basic approach, but the details are yet quite open.
