Yep - they originally gave me a complex polygon. I'm now using a set
of six rectangles that approximate the border instead.

Assuming a vaguely sane border the algorithm is OK I think. I'm sure

Planet could have the display name where people have made their edits
public, but currently doesn't. If you're reading the database then
obviously you can get it (or the numeric user id).
