Spam, and submissions

We have been having a lot of problem with spam coming to the email account we use to receive submissions. Therefore, effective immediately, you must put the word "Submission" in your email's subject line. If you do not, your email will be automatically deleted by our spam filter, and you will not receive a response. Our spam filter is inflexible and unforgiving - there are no exceptions to this rule. Sorry if this creates any hassle.
