I didn't see this anywhere else in the thread, though I could have missed it since there are a lot of posts. Near the bottom of their submissions page, they have the following:
"Though we expect writers to go by the standard rule of exclusive submissions, if, by chance, the work you submitted to us is also under consideration by another agency or management company, please let us know the status of that relationship as soon as it begins."
elsewhere on the page, they have:
"Based on your initial query letter and synopsis, our office may request sample chapters, your manuscript in its entirety, your nonfiction proposal or your completed screenplay. If your work is under consideration by another agency or management company, we ask that you let us know at that time."
So I'm assuming the first statement only refers to partials and fulls as exclusive submissions (a query is not a "submission" in this case). Is that how everyone else reads it?
