This site publishes short poems and short fiction, and you really need to read their submission guidelines yourself because they are thorough, which I appreciate. Essentially, you can send them an e-mail at righthandpointingATgmailDOTcom with a subject line such as “Submission: Your Name” and include 1-4 poems. Try to make sure they are less than 16 lines long, but if they go up to 20 lines then make sure there are no more than 75 words in the poem. They also have special issues with specific ideas and right now they are looking for especially short poems. Check out the details by using the link provided, and good luck on your submissions!
