Ok, if you haven't heard or been on the blue boards, aka Verla Kay's website, you must immediately go there. Don't pass Go. I'm addicted to them and wish I had discovered them sooner.
It's an online forum for writers, but agents and editors do pop in to chat. Yes, they are literally blue. The forums have categories by genre, response times for agents, publisher, and magazines, contest, and so much more.
There is a wealth of knowledge about the industry posted by writers in all stages of their careers.
