Instead of just query letters for novels, maybe you should request that people float their writing ideas in general past the Minions. Got an idea for a story, book, screenplay, Nanovel? Give it a query and send it out for the minions to chomp on. Maybe it will get more material incoming.
Not sure if you mean people should write the query letters for works they haven't finished (or even started), in order to get feedback on the concept rather than the query letter, while also getting feedback on what would be a rough draft of the query letter assuming the book turns out the way they currently envision it--in which case they would be sending standard query letters, or if you mean they should just lay out the concept (not in query-letter format) to get our opinions on how they can improve it or whether they should even bother trying.
I'm okay with either. Anyone who wants input from EE and his minions about anything you're writing or considering writing or have no intention of writing, don't be shy.
EE is not responsible for anything that happens to anyone as a result of this policy.
