I'm a postdoc and I have never submitted a research proposal.
There is a funding project at my current University open to postdocs. I have a list of past winners and I'm tempted to ask for their proposals to give me some guidelines in writing mine. Obviously I can just ask and I know that professors share winning proposals, but usually, they know each other. But I've never met these people and the only thing I have is their contact information.
What is the correct way to ask for sample proposals and is it considered good manners to ask such a thing?
