FlashFlood - a journal of flash stories for National Flash Fiction Day (16th May 2012) - wants your 500 word or less short stories. You can sub up until midnight on the 15th May.
I subbed yesterday and this is what I got back:
'Thank you for the beautiful story you've sent as a submission to FlashFlood the National Flash-Fiction Day journal. We’re pleased to say that we enjoyed your story and would like to publish it. It will appear on the journal blog, http://flashfloodjournal.
at around 4pm (BST) on 16th May 2012.
Please do tell people about your success, encourage them to submit their stories as well (submissions close at 23:59 on 15th May) and to read the journal once it goes live. Stories will be posted all day throughout National Flash-Fiction Day.'
