Giving a plug to a contest on Writing Sense because I like so much that entries "are limited" to 100, the fee ($23) is reasonable and, unusual in contests, after the judging they send "specific suggestions" on five categories:
• Proofing & Editing
• Writing Technique
• Plot Development
• Character Development
Maximum words per entry are 2,000 (could be a stand alone chapter from a book), and deadline is 4/11/2013 - time to edit a piece on your someday-shelve.
