Inch, a journal "devoted to tiny poems and tiny fiction," will be temporarily closing to submissions on October 15th. If you've got short poems (under 10 lines) or microfiction (no more than 750 words) you want to submit, make sure to do it before then. Their online submission manager makes it easy to submit. Payment is in contributor's copies, but you'll enjoy them.
Entries are currently being read for the Mona Schreiber Prize for Humorous Fiction and Nonfiction. There is a $5 entry fee, but if your story's funny enough, you could win one of the three prizes of $500, $250, or $100. The deadline is December 1st, and you can read some of the previous winning stories on the website.
For your haiku reading pleasure, there is a new issue of Shamrock online now (#11). And for your horror reading pleasure, the September issue of Niteblade is also live, including two haiku by yours truly. (Niteblade is still open to submissions for its annual print anthology, which pays $10 and a PDF copy.)
