I generally receive around 200+ submissions for every issue. I accept ten poems (or fifteen for the art issue). That means a lot of poems to read and reject. I don't always comment on rejections, mostly because I just don't have the time. Then how do I find out why my poem was rejected? you ask. Well, one of the best ways to find out whether a poem works or not is to participate in one of the many online poetry workshops that are available on the web.
Besides editing Autumn Sky Poetry, I also serve as the Site Admin Poets.org's discussion forum. Anyone can become a member and post poems there. It's a lovely community sponsored by The Academy of American Poets (Poets.org).
Occasionally, I will critique a poem on the forum that I find interesting. I make no promises, but if you're ever wondering why I've rejected one of your poems, you may find out if you are willing to participate at Poets.org.
However please remember: if you post poems for critique, you must also critique other people's poems. Lest you think this is too much work for the answers you'd like, I must politely disagree. One of the best ways to grow as a writer is to analyze the strengths and weaknesses of other people's writing. It sharpens every one of your skills: it increases your facility with reading and interpreting poems, it hones your ability to persuade with your writing, and it often gives you surprising insight into how language really works.
