This is the email invitation from CARBON:

Hello Robert,

We are happy to announce the appearance of Carbon Poker tournaments and player statistics on Official Poker Rankings (OPR).

If you don't yet have an Carbon Poker account, you can create one here and your statistics will automatically be available on OPR shortly after you finish your first tournament.

Carbon Poker welcomes US and International Players.
First deposit 100% up to $600 bonus code: UPTO600

Kind regards,
