FULT

anyone know how to set the fleet ship? I try to create a fleet and some small ship is the fleet ship instead of my capital ship. How do I set it?

Ok so I just got the game and am struggling to figure out how to accept missions from the Computer players in the game. For instance I receive a mission to destroy a building or something. How do you accept the mission and how do you know which civilization I am supposed to attack, where to attack, etc....??? Any help would be greatly appreciated.
