From the Carbon Lobby, I clicked Tournaments tab, then Special tab.
There is a tourney scheduled for May 31 4:00 ET. called
CarbonCasino $10,000 Freeroll - Trip to Vegas!
I guess all you need to qualify is to head over to the Casino tab and
risk $10 in the casino sometime between May 1st thru May 28th. I played
BlackJack for $1 for 10 hands to meet qualifying for the tournament.
