"frappr" map

[CathastrophiX]

Is the map "locked" so you only can add US cities?
I haven´t seen this map before, interesting.
I´ve wondered where Yuma was for example.

Edit: realized you must not use ÅÄÖ, only A-Z, tried with an a insted of an å, and then it worked!

Edit 2: Man, I´m up north compared to you guys, about the same latitude as Iqaluit on Baffin Island. Luckily the Gulf stream passes by and makes the climate warmer here. 8)
