I am happily immersed in the amazing online writer's conference, WriteOnCon. Haven't checked it out? It's chock-a-block with great information for those who write KidLit (the conference is rated MC-18: main character under 18).
Elana Johnson,Casey McCormick, Lisa and Laura Roecker, Shannon Messenger, and Jamie Harrington did an amazing job recruiting authors, agents, and editors. If you don't follow them, you should.
