Space and Time has recently reopened to fiction submissions (though they are still closed to poetry subs). They will be reading until August 5th, for stories up to 10,000 words. No simultaneous submissions, and payment for accepted stories is made at 1 cent per word.
On the Premises has just launched their 18th contest. The theme for this one is "Time." Stories between 1000 and 5000 words can be entered up until the deadline of September 28th. The three top prizes are $180, $140, and $100, with up to three honorable mentions receiving $40.
