n. (Also `missile address') The form used to
register a site with the USENET mapping project includes a blank
for longitude and latitude, preferably to seconds-of-arc accuracy.
This is actually used for generating geographically-correct maps of
USENET links on a plotter; however, it has become traditional to
refer to this as one's `ICBM address' or `missile address', and
many people include it in their sig block
with that name.
