SM, a new magazine specifically for single women raising their families, is open to freelance writers:
"SM Magazine publishes articles from freelance writers on a broad range of subjects of special interest to single mothers, including family law, health, diet and exercise, spirituality, saving and managing money, co-parenting and interpersonal relationships, lifestyle issues, etc. Editorial content addresses the concerns, interests, and problems of single mothers. The articles should teach, inspire, motivate, and inform. The editors are primarily interested in practical, service-oriented pieces that will help millions of single mothers improve their lives and become their own experts."
I'd say relationship and sexuality writers with single parenting experience would be welcome.
Submit your articles and queries to firstname.lastname@example.org.
