I am an intern for WOW! (Women on Writing) and am helping with aspects of the winter contest. Details are below. But also I thought it might be fun to let each other know about contests that we think others might be interested in. If so, this is the thread! Let's get our stuff out there! 
WINTER 2007-2008 FLASH FICTION CONTEST
OVERVIEW:
WOW!
hosts a (quarterly) writing contest every three months. The mission of
this contest is to inspire creativity, communication, and well-rewarded
recognition to contestants. The contest is open globally; age is of no
matter; and entries must be in English. We are open to all styles of
writing, although we do encourage you to take a close look at our guest
judge for the season (upper right hand column) and the flavor of our
sponsor, if you are serious about winning. We love creativity,
originality, and light-hearted reads. That's not to say that our guest
judge will feel the same... so go wild! Express yourself, and most of
all, let's have some fun!
WORD COUNT:
Maximum: 500
Minimum: 250
The title is not to be counted in your word count. We use MS Word's word count to determine the submitted entry's word count.
PROMPT:
OPEN PROMPT!
That’s right, this is your chance to shine, and get creative. You can
write about anything, as long as it’s within the word count and
fiction. So, dig out those stories you started way back when and tailor
them to the word count.
We’re open to any style and genre. From horror to romance! So, get creative, and most of all, have fun.
