How do I let guests bring a plus-one?

1. Open the RSVP sheet: press Edit on the RSVP card in Manage → Features, or type plus one in Search setup and features, which opens the sheet at the rule. On the website the search is in both rooms; in the app it is in Manage.
2. Set People per invitation, from 1 to 20.

The number counts the guest who answers. For a plus-one, enter 2: the guest and one other person. 1 means nobody extra, and the form asks about the guest alone. A new event starts at 6.

It is set only in the RSVP sheet, not in the Design room. It limits how many guests one invitation's answer can include; a number outside 1 to 20 is refused under the field, and the refusal goes as soon as the number fits. The event's overall Guest limit, in the same sheet, is separate.

To give one invitation a different number, open that guest on Manage → Guests and, under Invitation, use − and + under Can include up to. It can be more or fewer than the event's number, and Same as everyone puts them back on it. It is offered while the event takes RSVPs here. In an app version before 1.3, use − and + on that guest's row in Manage → Invite (from version 1.2.1; earlier versions set it on the guest's page in Guests). A guest who is not on the invite list gets the event's number; add them to the list, with the email they sign in with, to give them their own.
