Duel Monsters Unlimited

I looked for the game that can tag duel n single duel. When I open this site, I searched the game n I found this game. n i open it. But, it can't open until somebody tell me to Sign up n download site's program, when i signed up, it told me to confirm the account. After i confirmed, it told to download the program, after that, i installed, n i try again to join the host. Finally, it worked, i played there, i maked a new deck, n i played with someone in single duel n TAG duel. And i can see my icon n i can change it. I can't tell this much more about this game, coz i'm tired to write this topic. i'll give this link for who want to play at this site........http://www.byond.com
