Thanks Frank,
I updated the chart, i also included a link to itoworld where it shows the
current status of the area.   Will be great to see it grow. :)

I'm putting all the ITOworld Images in the mediafire folder
http://www.mediafire.com/?sharekey=3b30da6df5072902ab1eab3e9fa335ca900fe694bd9e8be6

And heres the picture of it
