Traduction - Croate-Anglais - Ma nema zasto da Vam bude zao... ne brinite se......

Why is "You" capitalized? This is not normal in English, but I see that it is capitalized in the original. If this is also not normal in Croatian, I think it's OK.

But something is wrong with "some signature are" - there is no plural here, and also, why "some"?

I agree. Some signatures are would be better, and also in english You would only be capitalized if we are talking with some terrible god and didn't want to anger HIM, or if there were more than one YOUSE (actually a word for more than one in some parts of the USA as well as Canada). Seriously, I suggest you don't capitalize the You and determine if the signatures are singular or plural.

You ili Vi na hrvatskom je znak postovanja i pristojnosti prilikom obracanja nepoznatoj osobi.
Potpisi ili signatures je bila greska za koju se zelim izviniti.
Hvala

You or Vi in Croatian is a singe of respect and culture when you communicated with a person you don't know. Signatures or potpisi was a honest mistake and I would like to apologias for that.
Thankyou

Hey, that is perfectly all right. I am sure that I would capitalize it in another language too. We English speakers are funny that way!

I didn’t get offended I just wonted to give explanation why did I use capital Y. Any
suggestion is more then welcome

dramati, could you let me handle this one, please?

Knezevicka, could you please edit your text? I don't know whether signature should be singular or plural.

Translation should be as much it is possible close to the original text...if in original was used word “neki” which in English is “some” I believe by using word “some” I did not make mistake, but I apologias for writing signatures singular when it should be plural I corrected it to "some signatures".

Well done - thanks, Knezevicka.
