Help with an idea for a system?

[Mudbill]

Yes, I've thought about this system a bit, but I figured it'd be very odd to only have every second co-ord mean anything. I might have to go with it if there's nothing else. I also had an idea resolving around using the room co-ord with the extension of _w for west etc, but that wouldn't work because they are linked to each other. One west would be another's east.

Hm, perhaps I can name them something like "x3y3_x3y2." Two co-ords that equal the door linking the two rooms. I wonder if I can pull that off.

If there's any other system that I just can't seem to realize, a headsup is of course much appreciated =)
