The first step is to create a new attendee type, this can be named “Invited” or “Complimentary” (or one of each). It should have the Invited option selected.
Any registration types attached to this profile will not be visible to regular users.
The next step is to enable some “costs” for this attendee type. This should pertain to an existing registration type such as “Full Registration” or “Day Registration.
The enabled cost will be, $0.00.
You can now distribute the unique link that has been generated for your invited attendee type (these are also generated for trade attendee types.) If a delegate follows this link they will be offered the enabled item costs.
Alternatively, you can select the actual complimentary/invited registration type for this delegate through the admin registration page.
