I recently participated (as a purchaser of services) in the Dzanc Creative Writing Sessions program and can't say enough good things about my experience.

I chose Flannery O'Connor Award-winner and Alimentum editor Peter Selgin to offer feedback on one of my more traditional-ish long shorts, and his feedback was thoughtful and thorough.

I recommend others participate in the program -- as Dzanc has emphasized, many of the instructors offer similar services as freelancers at higher rates. And the proceeds benefit Dzanc, a really critical independent press & community resource.
