All posts about characters, patrons, ships, vehicles, equipment, adventures, locations and backgrounds are assigned to this three categories and found in the submenu of the same names. Other unasignable posts about Traveller are found here, except pictures and diagrams, that are not part of a specific Traveller posts: They are in the Visual-category. It is reasonable that there will be more categories later. (i.e. IMTU, Amber Zone)
