The Dallas Poets Community and Illya's Honey poetry journal are sponsoring the 2013 Open Poetry Competition. There are three hefty prizes -- $300, $100, and $50 -- and an entry fee of $10 for one to three poems ($5 for each poem after that). All submissions must be made by snail mail, and the postmark deadline is June 15th.
tinywords is open for submissions again, and the editors just extended the deadline to June 1st. This is an open submission period, with no themes or restrictions.
