Carol Walters hooked me on the website. Once there you can sign up for the "Writing Lesson of the Month Network & Ning" I have received two monthly emails writing lessons and it so far I think it is fantastic. It is based on the 6 traits of writing and uses picture books as the backbone of the lesson. Also student examples are provided and requested, so you can send your students' examples. I have only browsed the lessons so far and would love to try some out.
