Beginning in September, Vacation.com will offer its members online training sessions on its various suppliers and programs. These one-hour sessions include "Engagement 101" for members not already enrolled in the Engagement marketing program, and "Amadeus Cruise," which teaches agents how to use the booking tool. The courses, six in all, are repeated throughout each month and schedules are updated weekly in Vacation.com's Agent Advancement Center. Because participation is limited, members are encouraged to register in advance. There is no charge to participate; agents must be members of Vacation.com. Visit [www.agentnet.com].
