Thanks for that insight. I would guess that most people using country codes would prefer them to be sports related. At the Olympics there were well over 100 countries involved in judo, which I specialise in, and I would have thought there would be at least a similar number of countries involved in most of the individual sports. I am sure adopting the IOC standard would be suitable for most photographers. Better still, would it be possible to build into PM the ability to use one of the three lists depending on needs?
Sorry again to be writing this in the wrong category.
