There aren't many South Africans, however I know a decent amount of Polish and I can speak Dutch.
Can I can represent either Poland or Netherlands.
If I can't join either then you can put me in a South African team with Australia or New Zealand since we are quite similar just that South Africa is much better in rugby and cricket
edit: My heritage is quite complex, leave it as that
My guess is when enough people sign up? Do you guys have to have this done today? Or can it wait a bit. Big events like this take time to setup and get rolling.
