In this spirit, I've decided to circulate a post with my own personal list of flash challenges and prompts. I'm sure there are certainly many more out there but these are the ones I frequent almost weekly and recommend as good quality stuff:
55 Word Challenge (Wednesdays)
Visual Dare (Wednesdays)
And there you have my list. Now, I will be the first to say that I can seldom manage to sneak all of these into a week (though I have before). As you can see, Fridays get a bit...intense. Still and all, if you've been bitten by the flash fiction bug, you know too much is never enough, eh? Well, good writing all and hoping to see you pop up on the contributor's list of all these great opportunities.
