Using EventCreate allows flexibility in how you use your Attendee List. It can be used as an Invitation List, a Registration List, or a Guest List.
We have the following classifications of attendees:
Not Yet Responded
Not Yet Invited (included with Not Yet Responded)
You can find these classifications under your Attendee List, then by clicking on the “…” tab and by sorting or selecting the preferred status.
What that means is that "Attendee List (ALL)" refers to anyone you've uploaded as an invitee (Not Yet Responded) and anyone who has registered for your event (Attending).
If you want to view a list of only those who have registered for your event, please use the Attendees Report or view the tab Attendee List > Attending. Once a guest registers, their status will be updated on the Attendee List (ALL).
