OpCode D: Delete a User

Opcode D: Delete a User

This opcode is used to delete a user from the VTS system. Both attendees (default) and exhibitor users can be deleted. If LookupByExternalUserID is specified as one (1), then the user is located based on the ExternalUserID value. Otherwise, the user is located based on EMailAddress. Several conditions would prevent an exhibitor user from being deleted, such as the person being a booth contact.
