You sometimes need to add a registrant without having to pay for their items.
This is useful for example to add speakers to your data and have all their registration information including their selection of options which would have a cost for regular participants.
Procedure
Go to your registration form, fill the participants' information and select all the options including those with a cost.
Click Pay now.
Select Skip payment as your payment method. This option is only visible to organizers.
Click Submit.
Your registration now appears in the data with paid options selected, and no transactions were necessary.
