RSVP lets users invite people to attend an event. Users create an 'rsvp' from an event on the drupal event.module calendar, send an invitation email to a list of people, and can the track who has looked at the invitation and thier responses. Invitees can view and reply without having user accounts.

Rsvp creators can be setup the rsvp to hide other attendees, allow attendees to send email messages to the group, or invite more attendees.
