At the time I registered at this site, authors were begging to have their work reviewed, asking "Where Have All the Reviewers Gone?". At that time it was mentioned that there was a site who reversed your idea and only let authors post stories if they were reviewers. For every two stories reviewed, you could post one, or some such thing. That idea was shot down in favor of an appeal to lurkers to begin reviewing, which I did, but it may be time to revisit it.
