I created a new conference and 4 types of registration.
Since it is in public (free) federal institution, free registration is mandatory (no payment, no taxes).
The question is “how to set up no payment for registrations?”
I don’t now exactely when and where It was marked in the configuration of the conference, and how to remove it. I also didn’t find here in the forum or in the user manual.
Sorry if I skip something, but I really need a help in this topic.
Thank you in advance.
