First, the 'Get Started!' button gives access to the Quickstart tutorial. Then, previous CodinGames' exercises have been ranked by difficulty, with a 'Solution' button that gives access to the participants' source code (by clicking on nicknames, as always). This button will also be used to add the spontaneous corrections we receive from members of the community.
Under the 'Discuss' button we will also soon add a mini forum dedicated to each exercise so that exchanges and dialogues can be encouraged with those who need a hand.
