Yes, non-customers will also be able to register and participate on the Zemax general discussion forum, and we would love to have you participate! In fact, we will be sending personal invitations to the most active users of this forum, to make sure that you feel welcome to continue connecting with peers through the Zemax community.
In addition to the general discussion forum, we are adding separate technical support forums that will be managed by Zemax engineers, and the supported forums will only be available to current customers. This is a new bonus for current customers, but won't change the overall forum capabilities for non-customers.
Director of Customer Success, Zemax
