NxtYear,
I am very interested in what you said in your post and was hoping to get a few more details.
What I take from your comment is that unlike
Noble/CD/BetFred and Party/Empire/etc where you can have an account at each skin and play on each, so long as you don't play on more than one at the same time, you can only have one account period at any one of the Tribeca skins...regardless whether you play them at the same time or not.
Am I hearing you correctly?
How did they find out? Did they stop you during the registration process? I have heard you can set up another account if you use a second e-mail address at some of the other sites.
