Helix does not take unsolicited submissions at this time and has no plans to do so.
Active and Associate members of SFWA are welcome to submit queries. Please give story length, submission history if any, and something to give us some idea what it's about.
Writers who are not SFWA members, but who have equivalent professional publication records, may also submit queries. If you are not sure what "professional publication" means in this context, check http://www.sfwa.org/org/qualify.htm. Please list your publishing credits in your initial query message.
Note that word: "query." Please do not send any sort of submissions without querying first. Emails bearing attachments of any sort will be deleted unopened unless previous arrangements have been made. Paper manuscripts will be discarded unopened, except that we may look inside for return postage and appropriate it for our own use.
Thank you for your understanding and cooperation.
The Editorial Staff
