I'm impressed at how this site is set up:
http://www.reviewfuse.com/how/You have to review others in order to post new poems, and the quality of your reviewed are evaluated by the writers you review. It's a very smart system, designed to promote thoughtful criticism. Add it to your list of writer resources.
Oh, and they're hosting a poetry contest. Write a 50 line poem on the topic of "a bull fighter", and you could win $50. No entry fee, you just need to write some peer reviews. Details here:
