You don't need to have a good understand of Korean or Chinese to become a translator. The individual lines of text needed to be translated are often short, and an understanding of the context, along with an online translator, can often be enough to provide a good translation.
Google translations should only be used as a guide. I'm not in need of people to blindly copy and paste from Google. If you submit translations that are completely nonsensical, you may lose access to the translation tool.
If you'd like to become a translator, send me a PM requesting access to use the translation tool
