Regions
(On lighter topic...) The page says that IARU regions "correspond with" the ITU regions.  I believe the regions are geographically identical with the corresponding ITU regions.  The exact definition of regions is available on the IARU web site, but is hard to find on the ITU site.  Does anyone know the history?  I presume that IARU chose to use the ITU definitions, but it is odd that their documentation is not written that way.  In the amateur radio context, it is not always clear when you should speak of IARU regions or ITU regions.  It might be worth a note here.
