it would be so helpful to have multiple registration types soi could put
so when i create event fees they can be different for different types of registraints
I'm happy to say that we do have that feature currently. In your event campaign you can set multiple fee types, and even limit the fees to only secondary registrants. When someone adds a guest, they'll have to choose which ticket type (like member ticket, or non-member ticket).
You can see some screenshots in the event payment walkthrough we have here.
