Summer is almost over (sigh) and a mom's thoughts turn towards getting organized for the school year. To help us get started, we welcome Jennifer Dulski, working mom of two and co-founder and the chief executive officer at Centerd.com, a web site designed to help groups (big groups, small groups, friends, volunteers, etc) get on the same page. While the Manic Mommies love the idea of getting more organized, one of us (Kristin) is worried it's going to be harder than ever to avoid volunteering at the school.
