Language translations of vQuiz

What about open transifex project (for ex. www.transifex.com/wdmtech/ ) so we could collaborative translate language files to other languages.

Obviously, such a job for you is an overload of resources. So, teamwork is a real way to get a bunch of language translations.

I'm making russian translation by myself, but I could add my files to the common cause.

I can do the Dutch. But can someone please tell me if there's an language file I can adjust? My quizes are in Dutch and I don't want English buttons showing. Thanks

The language files should be there: YOURSITEROOT/components/com_vquiz/language and there:
YOURSITEROOT/administrator/components/com_vquiz/language
Create here nl-NL or nl-BE folder, copy en-GB.* language files, rename it to nl-NL.* ones and translate what you want.

I don't know why vQuiz languge folders are inside component folders, but if nothing work you can copy language files to oficial places:
YOURSITEROOT/language
YOURSITEROOT/administrator/language

Or, you can create overrides in the Joomla backend: YOUSITEWWW.NL/administrator/index.php?option=com_languages&view=overrides

Select Dutch (Site) and go.

This is only for the backend. Is there a way to change the language in the frontend?

I told you.

Well, I obviously don't understand. But thanks for your time anyway. I;ll try to figure it out!
