OPIN offers the possibility to collect ideas from everyone interested in the question and to express their agreement or disagreement with the different proposals to facilitate the decision-making process.
In the Idea Challenge projects users can be active in two phases:
1. Phase: create and comment on ideas
2. Phase: agree / disagree with those ideas and comments to check out how everyone feels or to decide which idea to put into practice.
The initiator of the project can decide how many days / weeks each phase is going to last. Afterwards everyone can check out the list with all published ideas and see how many users voted for or against each of them:
