It looks really nice!!!

Maybe one thing to change: when I choose geant2.net domain the map of US 
is presented with the list of geant2 links. Only when I click on a link 
name then the map goes in correct direction. Maybe it would be better 
to show the map of the world at the beginning. It's a bit confusing when I 
select geant2 and see US map.
