@Everyone

Don't use directions such as "directly above" or "to the left of." This is SPACE- what is your up could be someone else's down or left. Two fleets could meet, and one might be thinking of the planet as "directly below them", while the other will be thinking it of as "directly in front of them." Saying a station is right above a planet- that's like saying it's in orbit. And obviously, you only have one station in orbit if you expect them to know which one you're talking about. Now I'm not trying to pick on you Duck- I just now really noticed it. 

Directions such as those are EXTREMELY relative in space- giving directions like left-right, up-down, etc., is like saying something is in space. DON'T- you're in space. Left and rights work in 2-D warfare or maps. If you're playing C&C, or Banished, or some other game, then sure, those are viable options- North, South, East, and West. It's a 2-D plane- there's a definite up and down. But we're in SPACE- a 3-D plane that extends in every direction possible so far that we could fly for a thousand years, and never reach the edge. Saying "directly above a planet" is about as accurate as saying the sandwich is in the kitchen... where there's a party ongoing and everyone has sandwiches. Which sandwich? Is it the one farthest to the North-Eastern corner? Is it the one closest to the roof? The one on the floor? 

You can continue roleplaying as if everything is 2-D ((I know; it's hard to think of the universe as 3-D, since we've been 2-D all our life)), but just know that I'll act as if you were speaking 2-D, in 3-D space... so my Valkians will tell you to either bugger off and stop trying to insult them, or give you actual coordinates. Space won't be navigated by north, east, west, or south, it'll be navigated by coordinates, perhaps being relative your homeworld, your homeworld's sun, or the Galactic Center. 

Just something to think about in your future posts. 

Also, if I remember right, 4-dimensional coordinates could be used for coordinated military movements. For example, giving the x, y, and z are just the first three digits of four- they give the coordinates of the spot. The fourth digit, the, let's say, T, is for "Time." So giving a 4, 6, 8, 100, may mean to the spot that is +four lightyears to the Galactic-North/South, +six lightyears to the Galactic-West/East, and +eight lightyears to the Galactic-Up/Down, and then the 100 may mean in 100 AS, or 100 After-Space (When you get into space as a spacefaring power). If you were in, say, 99 AS, and told multiple ships to be at certain coordinates at a certain time, then you'd have everyone in position at a precise point, in which you can beam communications, using a closed-circuit type that can only be communicated by if it actually hits a received, to your allies without giving yourself away. 

Just a thought.
