CiviEvent - Add Participants
You may find that you need to add participants to an event, such as those who sign up on a paper form or via fax. This is pretty easy to do.
Go to the Event menu and select Register Event Participant
This is very similar to the edit record that we looked at on the Find Participants how to, except that now we are adding a person.
You can choose to either add the event to someone already in your database or to create a new record. The new record pop-up will ask for the person's name and email. After you've added them and their event, you can go into their record and add more details.
You can also input volunteers, hosts, and speakers this way so that you can have them in your event participant register.
