Hello @jhoon,
I am letting know that Seungwan has not responded so far. I would propose to not wait longer. If Seungwan will be able to join, he can join here anytime. If you would like to translate not translated strings in the Korean translation file, I encourage to do that.
We have a translators guide that describes how to perform the translations and how the entire translation process goes. You can find it here:
https://bacularis.app/doc/contributions/translations.html
Described there step 3 is not necessary to do because we already have the Korean translation files.
If you will have any question or problem with translations, please let us know. You can write them here on this user group.
Thanks in advance for your work.
Best regards,
Marcin Haba (gani)
