And you know what that means, yes? Story a Day challenge is going on right now.
Seventh Sanctum has some great prompts, as well as Justin and his writing exercises on FM.
I can't seem to write a story that'll stay short enough for the markets. I blame it on my muse. But hey, if you're adventurous enough, you should go for it. On FM we even have a board set up to track your progress.
Good luck, folks!
