Le lien que tu asdonné est mort, mais je l'ai déjà lu donc c'est pas grâve donc voilà où j'en suis

Code :

je galere avec les pseudos donc j'ai fait comme ça (c'est pas grâve comme c'est en local)
*edit j'ai réussi pour les pseudos, mais y'a quelques gros bugs (peut être parce que je test 2 clients sur le même pc) maissi t'as ton code commodor je le veux bien
