I have a friend who got an email from an agent asking her to call - any time. I figured, "She's going to offer representation." I mean, isn't that the call we're all waiting to make? So anyway, she makes the call and it's a "NO". I don't get it. My friend is going to call me tonight and tell me what happened in that call. I'll keep you posted.
But BookEnds Agency had some good answers to questions about agents: http://bookendslitagency.blogspot.com/
