The Idea box is a useful tool for collecting ideas, but it it more than that. With the up and down arrows members can vote for the ideas, so in the same time of brainstorming, they can give feedback about others' ideas too, thus helping to choose the best option.
To create a new idea box, click on 'New tool' on the main page of the scene, and choose 'Idea box'.
Idea boxes can be found on the scene's main page, among the other tools. It is a dinamic tool for collecting ideas, because in the same time members can vote for ideas as well.
Members of the idea box can delete their own ideas, but the administrator (announcer) of the tool can moderate the ideas, and also delete them.
