When you start upload photos of Serbian plates in the future ongoing section, please remember of specific letters Ć, Č, Đ, Š and Ž! They should be clearly readable on photos.
Thanks for the advice, I will keep that in mind. I already sorted out my photos (around 1,5k!). Though I think those letters will be a problem for many users, especially Č and Ć which can be mixed up easily and Đ is sometimes barely readable on the plate.
