Hoi,
FYI we have a technical issue with Serbian.. The codes that are used are wrong. They have been chosen for whatever reason but technically they are only distinguishing Serbian in Latin and Cyrillic script. We cannot identify in this way and use instead dialectal differences. Technically this is wrong and it may become an argument in future to split Serbian. Correct codes would be sr-Cyrl and sr-Latn

Thanks is for trying to diffuse the Northern Luri thing.
