Diabolic Publications has a few anthologies coming up (linked at the bottom of the page), but I’ve showcased the June anthology, Dying to Live:
We will be publishing an anthology of vampire fiction Dying to Live in October 2013. Submissions are being accepted until June 1, 2013, which is a change from our original date of August. We are looking for dark vampire stories; please do not send any stories about vampires that sparkle!
They’re after 2,000 to 8,000 word submissions and i think payment is around 3 US cents/word.
