Sorry if this has been answered already. I was wondering how the ranking works? I have an account here on YGOPRO but it had me create a checkmate server account separate from this. I used my log in on the game and it let me in but I tried typing just random characters a second time, and it also let me in. So it seems like it doesn't matter what name or password you type in the game it lets you duel. So it seems like it doesn't let you use the account you created. Also its weird I have to separate accounts for here and then on the checkmate server.
