1. CC has freerolls
in ACR and BCP - rooms in the same network.
2. No, CC does not have freerolls in Ya Poker.
3. If you are a member of Jackpot Freerolls (or if you search for their passwords), they always list Ya Poker separately from Winner network, but in fact this is the same network and their Jackpot freerolls run in Ya Poker in the same way they appear in ACR or BCP.
So, try to increase your bankroll and if you want to remain in the same network - move the funds to ACR or BCP. (in my view, ACR has better promotions for new customers)
