I received an email about this a couple of weeks ago, although they weren't specific about what was going to happen. So Doyle's and Cake are now different skins on the same network, much like Party and Empire used to be.
I guess Doyle's was getting no traffic and the
Cake Poker Network must be 'on the up'. I noticed other skins like RedStar and CardSpike appearing recently, also on the same network.
The only thing that worries me about playing at Cake is that (according to BonusWhores at least) you can have multiple accounts. Do you know if this is this true David?
