I'm limited on space, so 5,000 words is the limit. It's not set in stone, but you'd have to write a zinger for me to take anything much longer. My goal is to reply in under four weeks. If you haven't heard anything by six weeks, feel free to query by letter or email. Enclose an SASE for a reply.
Disposable manuscripts are fine.
Cover letters are optional, but preferred. No SASE required for foreign submissions. I will reply via email to save on international postage. If you have doubts about your topic, please query.
