Re-challenge user

When an opponent deletes you on accident from your game you have to click on the X to archive the game if you don't it's like you're still playing them and when the 7 days are up you will not be able to re-challenge because the game is not archived. Then you go and select new game, and on the new game page you will see a link to see privious opponents, when you click on the opponent you just archived it will restart the seven days but it will work in order to re-challenge the opponent.
