This is a topic near and dear to my heart since it took me forever to notice--when you enter a one time contest the "flag" changes color from red to green)(it is covering the word one-time or lucky list. Green shows that you entered a one time contest already or added to your lucky list. If you haven't entered the contest or added it to your lucky list, it stays red. So why would you want to remove the entered flag?--because when you went to enter you weren't successful or got interrupted or whatever. Otherwise you might think you entered when you didn't actually succeed.
