In an open letter to members, Sernovitz says he is leaving the leadership role at the organization with "mixed emotions," but plans to remain an active member. He will return to consulting, speaking, teaching and writing. His first book, "Word of Mouth Marketing," was published in November. Susan Tibbitts, executive director--who joined the WOMMA staff more than a year ago--will manage the association, supported by WOMMA's recently expanded staff of eight association professionals. -- Tom Siebert
