My coworker, Alice Pope, has put together a list of requested "dos and don'ts" from writers to agents. (There is also a similar post on dos and don'ts for editors.) Definitely check out the lists and let your opinions fly on the comment boards.
Here are some examples of requests from writers:
- "Do tell us what we're doing well."
- "Do tell us if you just arent excited about something we submit to you."
- "Do be timely, clear and honest with your submission policies."
