I know this may seem strange, but me and several other of my friends (four to be exact) have a sort of secret communication code with each other. Like for instance, if one of our fleets arrive at another planet, to show we mean to attack and destroy, we spread our ships out, so they aren't easily killed. If their close together, their weapons arcs are limited, so the fleet is passing by the planet by coincedence, or something else.

Again, it may sound strange, but does any one do something like this with their friends?
