I thought GE was for Germany as well, but went and looked it up, GE is for Georgia, DE is Germany, aka Deutschland
I'd say it's both right, after looking again at wikipedia re. "Country codes G".
On the profile settings here it says use "international 2 character code" - but doesn't specify which one.
GE is right for Germany in NATO two-letter code, the NATO is international, so is right.
DE is only right in "ISO 3166-1 alpha-2" - "I" in "ISO" means international. That'd be the one used for URLs too.
The ISO has 167 members, NATO 31, so I spose ISO is a bit more international....
It's DEU in NATO three-letter code, GER in IOC country code..
And there's loads more... ICAO airport code prefix: ED, ET (!!), ICAO aircraft regis. prefix is D- like the license plate code.
Georgia's alternate abbreviations are GG and GEO.
Well, you'll have to bear with it, cos the software considers changing GE to DE as spam, maybe that was the problem.
