Should you have any questions not addressed by the sshg_promptfest's rules, schedule, and submission guidelines (scroll down to read them), please don't hesitate to direct them to sshg.promptfest [at] gmail [dot] com.
I can't wait to see what you've done with your prompts!
P.S. If you don't think that you'll make deadline, don't stress out; just let me know, and then sit back and enjoy the fest as a watcher. :)
