Cuatrochan
Cuatrochan is a Spanish imageboard with just a few boards. I don’t usually add non-english boards, but this one seems like a nice place.
Classic Chan
- Random
- Otaku
- Anime & Manga
Audiochan
This is a unique one: Audiochan is the first audio-imageboard, where anyone anonymously can make threads and comment with audio instead of plain text.
