Offline PO File
If I update translation file using gtranslate and create an update PO file, will it be accepted for translatewiki? Is there any criteria for offline translation approval?
Please read the guide at https://www.mediawiki.org/wiki/Help:Extension:Translate/Off-line_translation. Then submit a link to your translated po file here. After one successful submission, you will be given the rights to use Special:ImportTranslations yourself.
