If you are affiliated with another site you can still play. Once the games go up - if you don't see them you can't play in them. Send me a pm if that is the case but I doubt I will be able to do anything about it.
Yea unfortunately support cannot help you with this.
It means you came to CardsChat (or any other affiliate) before you signed up and used our link (or another affiliate's link) to sign up for GGPoker. So in a nutshell the only players who will not be able to participate are those who signed up directly with GGPoker.
This is not them being mean or stubborn - it is the only way their software works.
I will ask them before the games start if we can link unaffiliated players. My previous rep would do that in certain cases but she is no longer there.
