Thank you so much for the feedback.

The confirmation email being sent in Korean does look like a real bug. I had set English as the default, but it seems I missed this part. Thanks for pointing it out.

You're right that the word "Translation" can be misleading. For now, translations are meant to be done manually, but I'm also considering automatic translation in the future. Automatic translation can change the meaning you want to convey, so I'd still recommend translating posts yourself. But for convenience, I'm thinking about adding automatic translation.

Thanks again.
