I would like to remove myself from automatic sign up.

Hello, I am not sure whether other users are experiencing the same issue but I was automatically signed up for 9x9 and 10x10 connect four tournaments. It does not give me the option to remove myself so I do not register automatically for future tournaments. Is there a way around this or will I be forced to participate in all new tournaments going forward? When I checked on the tournament page it only gives me the option to register but since I have not registered I am confused why I received new tournament games automatically. Any help would be greatly appreciated.
