This board can contain all of those communications. The internet, in Remoor, is referred to as the Remoorian Online Network (R.O.N). We are in the age of electronics; Remoor is as well. It is hard to go very far without running into a smart phone, laptop, or text-enabled Pokedex. This board is meant to hold records of all those electronic conversations. Did your characters have an interesting conversation last night over text messages? Did their work send out an irritating e-mail that required a response? That sort of thing belongs in this board.
