How do I see all the events an attendee has been invited to?

First, click on Attendees at the top of your screen.

Then, use the search box to search for the attendee you have in mind.  Once you find him/her, click on the name.  You’ll be taken to a screen that looks like this.

Here, you can see a list of all the events the attendee has been invited to. If you’d like to see whether they registered or checked in, you will need to go into that event and check on their status.
