You can view all the participants in your event and their answers to any custom questions within this report. You can also see if registrants are on a team, whether they've created their fundraising page yet, and find information about their fundraising page if they have created one.
After selecting your event, choose the View Participants link.
One helpful use of this report is to download and print it right before your event, and use it for a sign-in list. Simply have your event participants give their name or present ID at check-in, and you can see whether they are registered by checking against this list. You'll also have any other vital information at your fingertips - for instance, if you're giving out t-shirts, and one of your questions was for participants' t-shirt size, you'll have that right with their name on your list.
