Take a look at this and go through it as a demo [login to view URL] To be considered for the project put Marlo is king in your bid and tell me who the final will be based on your prediction and who will win!! The user will continue to make predictions all the way to the final until they have a winner, like you have just done in the demo . Upon finishing the user will be promoted to share to facebook or twitter etc. This will generate a post saying something like "I think <team> will win the World Cup, who do you think will win? Click here to find out <link to the website>" It would be great of the post could contain an image showing the team who they think will win or an image to the game. I look forward to your bid
