What is Candiwi?
Candiwi is a new kind of wiki. The difference is that changes to an article are only made when other users accept them.
How does it work?
When you want to change something, you create a proposal, that will contain your changes. In your proposal you can propose changes to articles or add and remove articles.
All changes you make are displayed for other users to evaluate. Other users can also collaborate on your proposal.
When you're finished editing, you can submit it for everybody to vote on. If it is accepted, the changes are applied to the mainline.
