ParticiBox - The network of participatory boxes

ParticiBox is a free network of virtual participatory boxes.
A participatory box is a virtual box around a theme, a person, a city, etc. Participants fill the box with objects: posts, links, images, music or music playlists from Deezer, SoundCloud and Spotify, and videos or video playlists from Dailymotion, Vimeo and Youtube.
Users can create and manage as many participatory boxes as they want. They can view the content of the participatory boxes of other users. They can also participate in others' participatory boxes by subscribing with a single click (they then become participants).
The creator of a box is its administrator. He can validate the objects proposed by other participants before their publication, delete them if he deems them irrelevant.
Other users can vote for each object in the box and report it to the administrator if they think the object is out of place.
