I have three tanka in the May issue of Bamboo Hut, an online tanka magazine. I’m not entirely sure when it went live, and don’t think I ever received an acceptance e-mail, but they are nonetheless there.
Like MoonGarlic, the haiku journal I mentioned last week, this one uses Camaléo, which is kind of weird. Hit the “full screen” button to make the embedded widget a usable size.
