Before revision:  We limit the cardinality of the signal space to be less than the cardinality of the action space and the state space . This limits the sender's ability of making arbitrarily many action recommendations . We prove the existence of a solution to the sender's utility maximization problem and characterize its properties .
After revision:  We limit the cardinality of the signal space to be less than the cardinality of the action space and the state space , which limits the number of action recommendations that the sender can make. Existence of a maximum to the sender's utility maximization problem and characterize its properties .
