This project aims to introduce a system to introduce a suggestion-review system which would allow the community to contribute to the content on Oppia. It also aims to add a review system to allow easy management of the proposed suggestions and accept or reject them as appropriate. In order to maintain quality of reviews, we allow reviews from users who have made above a certain number of contributions in similar kind of suggestions. For each exploration the creator of the exploration can appoint some trusted reviewers who will be able to accept (merge) content related suggestions for that exploration. At a site-wide level, translation reviewers can be selected for each language and they can accept translations for that particular language.
