From Inkygirl reader Deborah Amadei :
I am starting up an online Nonfiction only childrens' writers critique group. The following categories are eligible: magazine articles, PB, middle grade, as well as proposals for middle grade nonfiction. We have our own google group, which is by invitation only. Starting the end of September/early October I will post the first invitation to submit. I will be requesting submissions every three weeks (one week for submission and two weeks for the critiques. ) For now I will limit submissions to a maximum of 10 pages.
If you are interested please e-mail me with a writing sample, which should include their categories to firstname.lastname@example.org.
