Yes, it's one of those days when the market links keep tumbling in - which makes it a great day! This time it's an anthology for "Oomph: A Little Super Goes a Long Way". They're looking for stories where your superhero has limited powers to save the day. 2000 to 8000 words, payment is a flat $20, and the deadline is January 15, 2013. You can find the details here http://crossedgenres.com/submissions/oomph/
And be sure to check out the site because Crossed Genres also publishes a magazine (with themes) and has other anthology calls still open.
