Anyone can help by suggesting new translations here. No need to use a Translation Editor, you can do it all from GlotPress!
Once you've suggested a new translation, a GlotPress validator will review it. They will then approve, reject, or change your suggestions. Once your changes get approved, they are automatically included in the next Meta Box release.
You can find detailed GlotPress documentation on this page.
If you can't find your language in GlotPress, send us an email and we'll add it for you.
== I want to change translations locally. Where can I download the .PO file for my language? ==
You'll find options to create a .PO file and export translations at the bottom of each language page in GlotPress.
