Icon for "Requests"? Vote!

Been asked to design an icon for "Requests", a feature where users can make a request for an item and another user can upload/respond with an answer to the request. This icon will lead users to the page where all the current requests are listed.

A vote or suggestion of something else would be helpful. I've tried many solutions and these are my top 3.
