In this episode of Behind the Membership Callie talks with Mark Warner about his membership site for teachers, Teaching Packs. Mark has a very different model to most membership site owners, offering only a very low cost non-recurring annual membership.  So we're talking about why Mark made that decision, and how it's enabled him to attract 15,000 teachers to his membership over the last five years, as well as completely transform his own life in the process. We're also talking about how Mark has spent 20 years building his audience, including an impressive three million Facebook page likes. And Mark discusses how he uses reviews and free resources to attract new members, and why, unlike most memberships, his members join for the content and stay for the content.
