I have a user that has pointed out that several of the 2nd level administrative divisions in Croatia are missing. He has provided me with a website that lists all the 2nd level divisions but I can't find a way to insert them myself, so I assume this is a bootstrap process. If so, how should the data be submitted for inclusion and what format is recommended/requested?
In addition you may want to use the EUDict to translate some of the text.

I was going to check the list against the list of administrative divisions. In the first document you are looking for entries in the "Općine:" sections.
