Yeah, that bit is incorrect. You want to go into Content/Strings/ and get and extract the StringsFromMaps.xnb file. In that file, you will add a line Place.#: "Message Content" #!String The in the map file, you will put on the building tile Action | Message Place.# For example, like "Town.1: "Clinic - Hours 9:00 AM - 3:00 PM" #!String" is line 324 in the strings file, and if you look in the town map, there is "Action | Message Town.1" on the clinic hours sign tile. Edit - I see Karmylla beat me to this... Although to clarify something she said, you do not HAVE to reference the specific map in the string file. Doing it by map is good practice for showing where the message is displayed, but not nessasary. For example, for my Expanded Access mod, I added several lines starting with "Expanded.#" beacause I wanted them listed together.
