Did you guys try it from the link I gave you?

Ok, Taadaa..this is what my letter says I received TODAY:

You're in luck Red Flush will allow US Players to register new accounts-all you have to do is follow procedure contained in this letter...
Visit www.playredflush.com  and fill out details   blah blah blah....

I gave you toll free number to get a promo code, or the support email address.

That is what they listed in the letter.  Maybe chat is not aware of this.

Maybe this is only available to High Rollers, I don't know.  But I would call, or email if I were you, and wanted an account.
They are given one to me.
Good Luck.
