Comment 3 for bug 566434

Oh well, there is always a way to talk (write) somebody to an exact location - sure.
I admit it's a luxury feature. I thought, as this already exists inside the editor (though permanently, which I wouldn't like in the game)
it might be easy to do.
A permanent marker would be seen by anybody participating in the game, and so less versatile.
We like to play 2 on 2 coalitions with 2 different teamspeak session, and I would primarily want the feature
to inform my partner about what I plan to do next.
But a decent way to reference a location would help for
other things, too - like bugs or replays etc.
