@Abi: Download the
UD Homecoming Beacon if you're using Firefox and install it. Make sure you allow that site to install stuff. Once it's installed go to
Tools -> Extensions. Highlight the UD Homecoming Beacon extension and select
Options at the bottom of the window. Type in your
X position as
45 and your
Y position as
15. Now when you play UD it should say
~23(APs)
to home (19N4E).
