Sirens Call Publications has posted two anthology calls. The first is a romance/erotica anthology titled "Flowers are Overated" with a deadline of December 31 (or when filled) and the second is a horror anthology titled "Fear of the Dark" which is open until filled. Both need stories of 4000 to 10,000 words, payment is royalties. You can find the details for both here.
