A large number of our exhibitors have been sent misleading information from Construct Data Publishers concerning their FAIR GUIDE. We have sent them a Cease and Desist letter from our legal counsel. The firm is notorious. In fact, the International Association of Exhibitions and Events has been fighting this group for years. There is an area on the IAEE website that can provide some guidance on how to react if you have been taken in by their pitch.
The Cease and Desist letter can be obtained here.
