It is determined that whether or not a user of the transmission destination is a registered member of a chat system using member information regarding the user of the transmission destination, and a chat method is generally selected as the communication method applied to the communication with the transmission destination when the transmission destination is the registered member. Oh the other hand, when the transmission destination is a non-registered member, a communication method other than the chat format is selected. |
