Check out their Writing Guidelines. Because they've worked hard to shorten up their response time, they have implemented a "theme" of the month. They have also decided to accept simultaneous submissions since "it is so darned difficult to get one's work published."
Glimmertrain's Short Story Writing Contest for New Writers will open November 1st, closing at midnight on the last day of the month. There is a $15 reading fee with first place receiving $1200 and 20 copies of the issue with the winning story.
If you submit a story during their "Standard" months, there is no reading fee. Payment is $700 for first publication and onetime anthology rights.
Order a copy today, familiarize yourself with the type of writing they print, and see if you're meant to submit your piece. Depending upon the month, they accept fiction all the way up to 20,000 words.
