It turns out I was able to deposit on Doyle's Room and play in this tourney.
I guess the rules changed once they moved to the Cake network.
One thing I would've like more clarification on is who are the bounties in the game.
When I played last night, it looked like Doyle Brunson was not playing.

I saw screennames for MIKE_CARO, HOYT_CORKINS, and a few people that had names started with TEX_

It appears that the bounties have names in all caps with an underscore but I think some of those TEX_ players were not bounties.
Just a little confusing.

I think the tourney lobby should clearly state who the bounties are or have their names shaded in particular color like FTP does.
